The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0340 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2020-27820:
    A vulnerability was found in Linux kernel, where a use-after-frees in nouveau/'s postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver).

    CVE-2021-0920:
    In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel

    CVE-2021-20321:
    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.

    CVE-2021-22543:
    An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation.

    CVE-2021-38160:
    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.

    CVE-2021-38199:
    fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which     allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for     those servers to be unreachable during trunking detection.

    CVE-2021-45868:
    In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file.

    CVE-2022-0617:
    A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2.

    CVE-2022-0850:
    A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace.

    CVE-2022-20421:
    In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-239630375References: Upstream kernel

    CVE-2022-2196:
    A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution     attacks.L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or     IBPBafter running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code     execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2     or past commit2e7eab81425a


    CVE-2022-2639:
    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2022-29581:
    Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions.

    CVE-2022-3567:
    A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects     the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to     race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier     assigned to this vulnerability.

    CVE-2022-3586:
    A flaw was found in the Linux kernels networking code. A use-after-free was found in the way the     sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and     freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a     denial of service.

    CVE-2022-4129:
    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service.

    CVE-2022-41858:
    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information.

    CVE-2022-4378:
    A stack overflow flaw was found in the Linux kernel/'s SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system.

    CVE-2023-0045:
    The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

    We recommend upgrading past commita664ec9158eeddd75121d39c9a0758016097fa96

    CVE-2023-0394:
    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash.

    CVE-2023-20938:
    In binder_transaction_buffer_release of binder.c, there is a possible use after free due to improper input     validation. This could lead to local escalation of privilege with no additional execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-257685302References: Upstream kernel

    CVE-2023-2513:
    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors.

    CVE-2023-30456:
    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4.

    CVE-2023-31436:
    qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX.

    CVE-2023-32269:
    An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability.

    CVE-2023-35001:
    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace

    CVE-2023-4128:
    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue.

    CVE-2022-0847:
    A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system.

    CVE-2023-2269:
    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1266-1 advisory.

  - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel     (CVE-2021-39713)

  - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file. (CVE-2021-45868)

  - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux     Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.
    (CVE-2022-0812)

  - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace. (CVE-2022-0850)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV     device frontends are using the grant table interfaces for removing access rights of the backends in ways     being subject to race conditions, resulting in potential data leaks, data corruption by malicious     backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the     gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they     assume that a following removal of the granted access will always succeed, which is not true in case the     backend has mapped the granted page between those two operations. As a result the backend can keep access     to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl()     printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had     been freed by gprinter_free(). (CVE-2020-27784)

  - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace. (CVE-2022-0850)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - In rndis_set_response of rndis.c, there is a possible out of bounds write due to an integer overflow. This     could lead to local escalation of privilege if a malicious USB device is attached with no additional     execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions:
    Android kernelAndroid ID: A-239842288References: Upstream kernel (CVE-2022-20423)

  - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the     machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector     (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is     disabled by default, it could allow an attacker to crash the system or have other memory-corruption side     effects. (CVE-2022-2938)

  - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

  - A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from     the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length     heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary     code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged     code on the target system to exploit this vulnerability. (CVE-2022-2991)

  - Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers     em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system     or potentially escalate their privileges on the system. (CVE-2022-3239)

  - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead     to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or     member of the audio group) could use this flaw to crash the system, resulting in a denial of service     condition (CVE-2022-3303)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations. (CVE-2022-39189)

  - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a     race condition with a resultant use-after-free. (CVE-2022-40307)

  - roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition     and resultant use-after-free in certain situations where a report is received while copying a     report->value is in progress. (CVE-2022-41850)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.

    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote OracleVM system is missing necessary patches to address security updates:

  - The imon_probe function in drivers/media/rc/imon.c in the Linux kernel through 4.13.11 allows local users     to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified     other impact via a crafted USB device. (CVE-2017-16537)

  - In the Linux kernel before 4.13.5, a local user could create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of service. (CVE-2017-18270)

  - The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service     (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.
    (CVE-2017-7472)

  - In get_futex_key of futex.c, there is a use-after-free due to improper locking. This could lead to local     escalation of privilege with no additional privileges needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel Android ID: A-74250718 References: Upstream     kernel. (CVE-2018-9422)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A flaw was found in the Linux kernel in versions before 5.9-rc6. When changing screen size, an out-of-     bounds memory write can occur leading to memory corruption or a denial of service. Due to the nature of     the flaw, privilege escalation cannot be fully ruled out. (CVE-2020-14390)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
    (CVE-2021-43976)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace. (CVE-2022-0850)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to     restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently     allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass     verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and     unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for     peripherals that do not verify firmware updates. We recommend upgrading past commit     4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)

  - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
    (CVE-2022-2964)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0339 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2020-27820:
    A vulnerability was found in Linux kernel, where a use-after-frees in nouveau/'s postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver).

    CVE-2021-0920:
    In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel

    CVE-2021-20321:
    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.

    CVE-2021-22543:
    An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation.

    CVE-2021-38160:
    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.

    CVE-2021-38199:
    fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which     allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for     those servers to be unreachable during trunking detection.

    CVE-2021-45868:
    In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file.

    CVE-2022-0617:
    A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2.

    CVE-2022-0850:
    A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace.

    CVE-2022-20421:
    In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-239630375References: Upstream kernel

    CVE-2022-2196:
    A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution     attacks.L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or     IBPBafter running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code     execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2     or past commit2e7eab81425a

    CVE-2022-2639:
    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2022-29581:
    Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions.

    CVE-2022-3567:
    A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects     the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to     race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier     assigned to this vulnerability.

    CVE-2022-3586:
    A flaw was found in the Linux kernels networking code. A use-after-free was found in the way the     sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and     freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a     denial of service.

    CVE-2022-4129:
    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service.

    CVE-2022-41858:
    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information.

    CVE-2022-4378:
    A stack overflow flaw was found in the Linux kernel/'s SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system.

    CVE-2023-0045:
    The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

    We recommend upgrading past commita664ec9158eeddd75121d39c9a0758016097fa96

    CVE-2023-0394:
    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash.

    CVE-2023-1076:
    A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters.

    CVE-2023-20938:
    In binder_transaction_buffer_release of binder.c, there is a possible use after free due to improper input     validation. This could lead to local escalation of privilege with no additional execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-257685302References: Upstream kernel

    CVE-2023-2513:
    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors.

    CVE-2023-30456:
    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4.

    CVE-2023-31436:
    qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX.

    CVE-2023-32269:
    An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability.

    CVE-2023-35001:
    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace

    CVE-2023-4128:
    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue.

    CVE-2022-0847:
    A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system.

    CVE-2023-2269:
    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component.
