The version of AOS installed on the remote host is prior to 5.19.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

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

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3929-1 advisory.

    The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes.

    The following security bugs were fixed:

    - Unprivileged BPF has been disabled by default to reduce attack surface as too many security issues have     happened in the past (jsc#SLE-22573)

      You can reenable via systemctl setting /proc/sys/kernel/unprivileged_bpf_disabled to 0.
    (kernel.unprivileged_bpf_disabled = 0)

    - CVE-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may     have allowed unauthorized disclosure of information to an attacker with local user access via a side-     channel analysis (bnc#1068032). Additional spectrev1 fixes were added to the eBPF code.
    - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an     unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by     a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose     group ownership is that group. The intended behavior was that the non-member can trigger creation of a     directory (but not a plain file) whose group ownership is that group. The non-member can escalate     privileges by making the plain file executable and SGID (bnc#1087082 bnc#1100416 bnc#1129735).
    - CVE-2018-16882: A use-after-free issue was found in the way the KVM hypervisor processed posted     interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error     while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc'     descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this     flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel     versions and are vulnerable (bnc#1119934).
    - CVE-2020-0429: In l2tp_session_delete and related functions of l2tp_core.c, there is possible memory     corruption due to a use after free. This could lead to local escalation of privilege with System execution     privileges needed. User interaction is not needed for exploitation (bnc#1176724).
    - CVE-2020-12655: An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux     kernel Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka     CID-d0c7feaf8767 (bnc#1171217).
    - CVE-2020-14305: An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over     IP H.323 connection tracking functionality handled connections on ipv6 port 1720. This flaw allowed an     unauthenticated remote user to crash the system, causing a denial of service. The highest threat from this     vulnerability is to confidentiality, integrity, as well as system availability (bnc#1173346).
    - CVE-2020-3702: Specifically timed and handcrafted traffic can cause internal errors in a WLAN device     that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure     over the air for a discrete set of traffic (bnc#1191193).
    - CVE-2021-20265: A flaw was found in the way memory resources were freed in the unix_stream_recvmsg     function in the Linux kernel when a signal was pending. This flaw allowed an unprivileged local user to     crash the system by exhausting available memory. The highest threat from this vulnerability is to system     availability (bnc#1183089).
    - CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-     ioctl.c in the Multi-device driver module in the Linux kernel A bound check failure allowed an attacker     with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system     crash or a leak of internal kernel information. The highest threat from this vulnerability is to system     availability (bnc#1192781).
    - CVE-2021-33033: The Linux kernel has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c     because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd.
    This leads to writing an arbitrary value (bnc#1186109 bnc#1186390 bnc#1188876).
    - CVE-2021-34556: In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive     information from kernel memory via a Speculative Store Bypass side-channel attack because the protection     mechanism neglects the possibility of uninitialized memory locations on the BPF stack (bnc#1188983).
    - CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device fails  (bsc#1191961).
    - CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).
    - CVE-2021-35477: In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive     information from kernel memory via a Speculative Store Bypass side-channel attack because a certain     preempting store operation did not necessarily occur before a store operation that has an attacker-     controlled value (bnc#1188985).
    - CVE-2021-3640: Fixed a Use-After-Free vulnerability in function sco_sock_sendmsg() in the bluetooth     stack (bsc#1188172).
    - CVE-2021-3653: A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw     occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a     nested guest (L2). Due to improper validation of the 'int_ctl' field, this issue could allow a malicious     L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2     guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire     system, leak of sensitive data or potential guest-to-host escape. (bnc#1189399).
    - CVE-2021-3655: A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing     size validations on inbound SCTP packets may have allowed the kernel to read uninitialized memory     (bnc#1188563).

    - CVE-2021-3679: A lack of CPU resource in the tracing module functionality was found in the way user uses     trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use     this flaw to starve the resources causing denial of service (bnc#1189057).
    - CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel calls unregister_netdev     without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free     (bnc#1188601).
    - CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/cls_route.c (bsc#1190349).
    - CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can reveal files (bsc#1189706).
    - CVE-2021-3752: Fixed a use after free vulnerability in the Linux kernel's bluetooth module.
    (bsc#1190023)
    - CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#1190025).
    - CVE-2021-37576: arch/powerpc/kvm/book3s_rtas.c on the powerpc platform allowed KVM guest OS users to     cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e (bnc#1188838 bnc#1190276).
    - CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c. (CVE-2020-8648)

  - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the kernel context. This affects     arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior.

  - An issue was discovered in the Linux kernel before     5.2.6. On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault     statistics are inappropriately freed, aka     CID-16d51a590a8c.(CVE-2019-20934)

  - A flaw was found in the Linux kernels implementation of     MIDI, where an attacker with a local account and the     permissions to issue an ioctl commands to midi devices,     could trigger a use-after-free. A write to this     specific memory while freed and before use could cause     the flow of execution to change and possibly allow for     memory corruption or privilege     escalation.(CVE-2020-27786)

  - An issue was discovered in romfs_dev_read in     fs/romfs/storage.c in the Linux kernel before 5.8.4.
    Uninitialized memory leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)

  - In the Android kernel in Pixel C USB monitor driver     there is a possible OOB write due to a missing bounds     check. This could lead to local escalation of privilege     with System execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2019-9456)

  - A stack information leak flaw was found in s390/s390x     in the Linux kernel's memory manager functionality,     where it incorrectly writes to the     /proc/sys/vm/cmm_timeout file. This flaw allows a local     user to see the kernel data.(CVE-2020-10773)

  - A pivot_root race condition in fs/namespace.c in the     Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before     4.19.119, and 5.x before 5.3 allows local users to     cause a denial of service (panic) by corrupting a     mountpoint reference counter.(CVE-2020-12114)

  - An out-of-bounds memory write flaw was found in how the     Linux kernel's Voice Over IP H.323 connection tracking     functionality handled connections on ipv6 port 1720.
    This flaw allows an unauthenticated remote user to     crash the system, causing a denial of service. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-14305)

  - Use-after-free vulnerability in fs/block_dev.c in the     Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging     improper access to a certain error     field.(CVE-2020-15436)

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

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

  - mwifiex_cmd_802_11_ad_hoc_start in     drivers/net/wireless/marvell/mwifiex/join.c in the     Linux kernel through 5.10.4 might allow remote     attackers to execute arbitrary code via a long SSID     value, aka CID-5c455c5ab332.(CVE-2020-36158)

  - Incomplete cleanup from specific special register read     operations in some Intel(R) Processors may allow an     authenticated user to potentially enable information     disclosure via local access.(CVE-2020-0543)

  - An infinite loop issue was found in the vhost_net     kernel module in Linux Kernel up to and including     v5.1-rc6, while handling incoming packets in     handle_rx(). It could occur if one end sends packets     faster than the other end can process them. A guest     user, maybe remote one, could use this flaw to stall     the vhost_net kernel thread, resulting in a DoS     scenario.(CVE-2019-3900)

  - In pppol2tp_connect, there is possible memory     corruption due to a use after free. This could lead to     local escalation of privilege with System execution     privileges needed. User interaction is not needed for     exploitation. Product: Android. Versions: Android     kernel. Android ID: A-38159931.(CVE-2018-9517)

  - A flaw was found in the fix for CVE-2019-11135, in the     Linux upstream kernel versions before 5.5 where, the     way Intel CPUs handle speculative execution of     instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected     by the TAA flaw (TAA_NO=0), but is not affected by the     MDS issue (MDS_NO=1), the guest was to clear the     affected buffers by using a VERW instruction mechanism.
    But when the MDS_NO=1 bit was exported to the guests,     the guests did not use the VERW mechanism to clear the     affected buffers. This issue affects guests running on     Cascade Lake CPUs and requires that host has 'TSX'     enabled. Confidentiality of data is the highest threat     associated with this vulnerability.(CVE-2019-19338)

  - There is a use-after-free in kernel versions before 5.5     due to a race condition between the release of     ptp_clock and cdev while resource deallocation. When a     (high privileged) process allocates a ptp device file     (like /dev/ptpX) and voluntarily goes to sleep. During     this time if the underlying device is removed, it can     cause an exploitable condition as the process wakes up     to terminate and clean all attached files. The system     crashes due to the cdev structure being invalid (as     already freed) which is pointed to by the     inode.(CVE-2020-10690)

  - Improper input validation in BlueZ may allow an     unauthenticated user to potentially enable escalation     of privilege via adjacent access.(CVE-2020-12351)

  - A flaw was found in the Linux kernels implementation of     MIDI, where an attacker with a local account and the     permissions to issue an ioctl commands to midi devices,     could trigger a use-after-free. A write to this     specific memory while freed and before use could cause     the flow of execution to change and possibly allow for     memory corruption or privilege     escalation.(CVE-2020-27786)

  - use-after-free read in sunkbd_reinit in     drivers/input/keyboard/sunkbd.c(CVE-2020-25669)

  - A flaw was found in the way RTAS handled memory     accesses in userspace to kernel communication. On a     locked down (usually due to Secure Boot) guest system     running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to     further increase their privileges to that of a running     kernel.(CVE-2020-27777)

  - A locking inconsistency issue was discovered in the tty     subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may     allow a read-after-free attack against TIOCGSID, aka     CID-c8bcd9c5be24.(CVE-2020-29660)

  - A locking issue was discovered in the tty subsystem of     the Linux kernel through 5.9.13.
    drivers/tty/tty_jobctrl.c allows a use-after-free     attack against TIOCSPGRP, aka     CID-54ffccbf053b.(CVE-2020-29661)

  - An out-of-bounds memory write flaw was found in how the     Linux kernel's Voice Over IP H.323 connection tracking     functionality handled connections on ipv6 port 1720.
    This flaw allows an unauthenticated remote user to     crash the system, causing a denial of service. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-14305)

  - An issue was discovered in the Linux kernel before     5.2.6. On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault     statistics are inappropriately freed, aka     CID-16d51a590a8c.(CVE-2019-20934)

  - IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors     could allow a local user to obtain sensitive     information from the data in the L1 cache under     extenuating circumstances. IBM X-Force ID:
    189296.(CVE-2020-4788)

  - A flaw memory leak in the Linux kernel performance     monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this     flaw to starve the resources causing denial of     service.(CVE-2020-25704)

  - An issue was discovered in kmem_cache_alloc_bulk in     mm/slub.c in the Linux kernel before 5.5.11. The     slowpath lacks the required TID increment, aka     CID-fd4d9c7d0c71.(CVE-2020-29370)

  - A slab-out-of-bounds read in fbcon in the Linux kernel     before 5.9.7 could be used by local attackers to read     privileged information or potentially crash the kernel,     aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for     manipulations such as font height.(CVE-2020-28974)

  - A buffer over-read (at the framebuffer layer) in the     fbcon code in the Linux kernel before 5.8.15 could be     used by local attackers to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)

  - An issue was discovered in romfs_dev_read in     fs/romfs/storage.c in the Linux kernel before 5.8.4.
    Uninitialized memory leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)

  - Use-after-free vulnerability in fs/block_dev.c in the     Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging     improper access to a certain error     field.(CVE-2020-15436)

  - A flaw was found in the way RTAS handled memory     accesses in userspace to kernel communication. On a     locked down (usually due to Secure Boot) guest system     running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to     further increase their privileges to that of a running     kernel.(CVE-2020-27777)

  - An issue was discovered in romfs_dev_read in     fs/romfs/storage.c in the Linux kernel before 5.8.4.
    Uninitialized memory leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)

  - An issue was discovered in kmem_cache_alloc_bulk in     mm/slub.c in the Linux kernel before 5.5.11. The     slowpath lacks the required TID increment, aka     CID-fd4d9c7d0c71.(CVE-2020-29370)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c.(CVE-2020-8648)

  - A buffer over-read (at the framebuffer layer) in the     fbcon code in the Linux kernel before 5.8.15 could be     used by local attackers to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs     filesystem image, performing some operations, and then     making a syncfs system call can lead to a     use-after-free in __mutex_lock in     kernel/locking/mutex.c. This is related to     mutex_can_spin_on_owner in kernel/locking/mutex.c,
    __btrfs_qgroup_free_meta in fs/btrfs/qgroup.c, and     btrfs_insert_delayed_items in     fs/btrfs/delayed-inode.c.(CVE-2019-19813)

  - gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c     in the rpcsec_gss_krb5 implementation in the Linux     kernel through 5.6.10 lacks certain domain_release     calls, leading to a memory leak.(CVE-2020-12656)

  - A flaw was found in the Linux kernels implementation of     MIDI, where an attacker with a local account and the     permissions to issue an ioctl commands to midi devices,     could trigger a use-after-free. A write to this     specific memory while freed and before use could cause     the flow of execution to change and possibly allow for     memory corruption or privilege     escalation.(CVE-2020-27786)

  - A flaw memory leak in the Linux kernel performance     monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this     flaw to starve the resources causing denial of     service.(CVE-2020-25704)

  - A flaw was found in the Linux Kernel before 5.8-rc6 in     the ZRAM kernel module, where a user with a local     account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - A vulnerability was found in the Linux Kernel where the     function sunkbd_reinit having been scheduled by     sunkbd_interrupt before sunkbd being freed. Though the     dangling pointer is set to NULL in sunkbd_disconnect,     there is still an alias in sunkbd_reinit causing Use     After Free.(CVE-2020-25669)

  - A flaw was found in the Linux kernel. A use-after-free     was found in the way the console subsystem was using     ioctls KDGKBSENT and KDSKBSENT. A local user could use     this flaw to get read memory access out of bounds. The     highest threat from this vulnerability is to data     confidentiality.(CVE-2020-25656)

  - The Linux kernel before version 5.8 is vulnerable to a     NULL pointer dereference in     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init
    _ports() that allows local users to cause a denial of     service by using the p->serial_in pointer which     uninitialized.(CVE-2020-15437)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - A stack information leak flaw was found in s390/s390x     in the Linux kernel's memory manager functionality,     where it incorrectly writes to the     /proc/sys/vm/cmm_timeout file. This flaw allows a local     user to see the kernel data.(CVE-2020-10773)

  - ** DISPUTED ** drivers/gpu/drm/radeon/radeon_display.c     in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer     dereference. NOTE: A third-party software maintainer     states that the work queue allocation is happening     during device initialization, which for a graphics card     occurs during boot.

    (CVE-2020-10732)

  - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS     client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause     a kernel panic. The highest threat from this vulnerability is to data confidentiality and system     availability. (CVE-2020-10742)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c     has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,     aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability     because the issue is a bug in parsing mount options which can only be specified by a privileged user, so     triggering the bug does not grant any powers not already held.. (CVE-2020-11565)

  - 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)
