The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2892-1 advisory.

  - A use-after-free flaw was found in the Linux kernel's core dump subsystem. This flaw allows a local user     to crash the system. Only if patch 390031c94211 (coredump: Use the vma snapshot in fill_files_note) not     applied yet, then kernel could be affected. (CVE-2023-1249)

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-7077 advisory.

  - 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-2023-31436)

  - A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In     this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on     hdev devices. (CVE-2023-1989)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. When u32_change() is called on an existing filter, the whole     tcf_result struct is always copied into the new instance of the filter. This causes a problem when     updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the     success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading     to a use-after-free. We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.
    (CVE-2023-4208)

  - An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process. (CVE-2023-31084)

  - A flaw was found in pfn_swap_entry_to_page in memory management subsystem in the Linux Kernel. In this     flaw, an attacker with a local user privilege may cause a denial of service problem due to a BUG statement     referencing pmd_t x. (CVE-2023-4732)

  - A flaw was found in KVM AMD Secure Encrypted Virtualization (SEV) in the Linux kernel. A KVM guest using     SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke     the `VMGEXIT` handler recursively. If an attacker manages to call the handler multiple times, they can     trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel     configurations without stack guard pages (`CONFIG_VMAP_STACK`). (CVE-2023-4155)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this     vulnerability is the function intr_callback of the file drivers/net/usb/r8152.c of the component BPF. The     manipulation leads to logging of excessive data. The attack can be launched remotely. It is recommended to     apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211363.
    (CVE-2022-3594)

  - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or commit     739790605705ddcf18f21782b9c99ad7d53a8c11 (CVE-2023-0458)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. When fw_change() is called on an existing filter, the whole tcf_result     struct is always copied into the new instance of the filter. This causes a problem when updating a filter     bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path,     decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-     free. We recommend upgrading past commit 76e42ae831991c828cffa8c37736ebfb831ad5ec. (CVE-2023-4207)

  - Information exposure through microarchitectural state after transient execution in certain vector     execution units for some Intel(R) Processors may allow an authenticated user to potentially enable     information disclosure via local access. (CVE-2022-40982)

  - A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware     Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system     due to a race problem. This vulnerability could even lead to a kernel information leak problem.
    (CVE-2023-1855)

  - The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects. (CVE-2023-1998)

  - A use-after-free(UAF) vulnerability was found in function 'vmw_execbuf_tie_context' in     drivers/gpu/vmxgfx/vmxgfx_execbuf.c in Linux kernel's vmwgfx driver with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-40133)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

  - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

  - A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to     cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the     TDP MMU are enabled. (CVE-2022-45869)

  - A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when     plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to     the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED     controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led     structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
    (CVE-2023-1079)

  - 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-2023-2513)

  - A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - A vulnerability, which was classified as critical, was found in Linux Kernel. Affected is the function     l2cap_conn_del of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads     to use after free. It is recommended to apply a patch to fix this issue. The identifier of this     vulnerability is VDB-211944. (CVE-2022-3640)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in     drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a     crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)

  - A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

  - A use-after-free(UAF) vulnerability was found in function 'vmw_cmd_res_check' in     drivers/gpu/vmxgfx/vmxgfx_execbuf.c in Linux kernel's vmwgfx driver with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-38457)

  - There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_parse_conf_req     function which can be used to leak kernel pointers remotely. We recommend upgrading past commit     https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e     https://www.google.com/url (CVE-2022-42895)

  - A flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was     found in the way user can guess location of exception stack(s) or other important data. A local user could     use this flaw to get access to some important data with expected location in memory. (CVE-2023-0597)

  - A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
    (CVE-2023-3212)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c. (CVE-2023-35823)

  - 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-2023-30456)

  - The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device.
    (CVE-2023-33203)

  - A race condition vulnerability was found in the vmwgfx driver in the Linux kernel. The flaw exists within     the handling of GEM objects. The issue results from improper locking when performing operations on an     object. This flaw allows a local privileged user to disclose information in the context of the kernel.
    (CVE-2023-33951)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c. (CVE-2023-35824)

  - A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

  - A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service. (CVE-2023-3161)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to     achieve local privilege escalation. When route4_change() is called on an existing filter, the whole     tcf_result struct is always copied into the new instance of the filter. This causes a problem when     updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the     success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading     to a use-after-free. We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.
    (CVE-2023-4206)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - A double-free vulnerability was found in the vmwgfx driver in the Linux kernel. The flaw exists within the     handling of vmw_buffer_object objects. The issue results from the lack of validating the existence of an     object prior to performing further free operations on the object. This flaw allows a local privileged user     to escalate privileges and execute code in the context of the kernel. (CVE-2023-33952)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2023:0114 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-3108:
    An issue was discovered in the Linux kernel through 5.16-rc6. kfd_parse_subtype_iolink in     drivers/gpu/drm/amd/amdkfd/kfd_crat.c lacks check of the return value of kmemdup().

    CVE-2023-2006:
    A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC     bundles. This issue results from the lack of proper locking when performing operations on an object. This     may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel.

    CVE-2023-2156:
    A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system.

    CVE-2023-3090:
    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in     the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend     upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.

    CVE-2023-31084:
    An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process.

    CVE-2023-3111:
    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag().

    CVE-2023-3117:
    A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and     anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel     memory. This flaw allows a local user with CAP_NET_ADMIN capability to crash or potentially escalate their     privileges on the system.

    CVE-2023-3161:
    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service.

    CVE-2023-3212:
    A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.

    CVE-2023-35823:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c.

    CVE-2023-35824:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c.

    CVE-2023-35828:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in     renesas_usb3_remove in drivers/usb/gadget/udc/renesas_usb3.c.

    CVE-2023-35829:
    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in rkvdec_remove in     drivers/staging/media/rkvdec/rkvdec.c.

    CVE-2023-3609:
    A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.

    CVE-2023-3610:
    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795.

    CVE-2023-3611:
    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.

    CVE-2023-3773:
    A flaw was found in the Linux kernels IP framework for transforming packets (XFRM subsystem). This     issue may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of     XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data     to userspace.

    CVE-2023-3776:
    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.

    CVE-2023-3812:
    An out-of-bounds memory access flaw was found in the Linux kernels TUN/TAP device driver functionality     in how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw     allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2023-4004:
    A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the     nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local     user to crash the system or potentially escalate their privileges on the system.

    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-2023-4147:
    A use-after-free flaw was found in the Linux kernels Netfilter functionality when adding a rule with     NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
