The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1773139548 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: virtio_net: fix xdp_rxq_info bug after     suspend/resume The following sequence currently causes a driver bug warning when using virtio_net: # ip     link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set     eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138     xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac
    __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64     do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely     (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets     up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down()     and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to     xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the     future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the     missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if     netif_running(). However, this should not make any functional difference since the refill work should only     be active if the network interface is actually up. (CVE-2022-49687)

  - In the Linux kernel, the following vulnerability has been resolved: scsi: libsas: Fix use-after-free bug     in smp_execute_task_sg() When executing SMP task failed, the smp_execute_task_sg() calls del_timer() to     delete slow_task->timer. However, if the timer handler sas_task_internal_timedout() is running, the     del_timer() in smp_execute_task_sg() will not stop it and a UAF will happen. The process is shown below:
    (thread 1) | (thread 2) smp_execute_task_sg() | sas_task_internal_timedout() ... | del_timer() | ... | ...
    sas_free_task(task) | kfree(task->slow_task) //FREE| | task->slow_task->... //USE Fix by calling     del_timer_sync() in smp_execute_task_sg(), which makes sure the timer handler have finished before the     task->slow_task is deallocated. (CVE-2022-50422)

  - In the Linux kernel, the following vulnerability has been resolved: xhci: Remove device endpoints from     bandwidth list when freeing the device Endpoints are normally deleted from the bandwidth list when they     are dropped, before the virt device is freed. If xHC host is dying or being removed then the endpoints     aren't dropped cleanly due to functions returning early to avoid interacting with a non-accessible host     controller. So check and delete endpoints that are still on the bandwidth list when freeing the virt     device. Solves a list_del corruption kernel crash when unbinding xhci-pci, caused by xhci_mem_cleanup()     when it later tried to delete already freed endpoints from the bandwidth list. This only affects hosts     that use software bandwidth checking, which currenty is only the xHC in intel Panther Point PCH (Ivy     Bridge) (CVE-2022-50470)

  - In the Linux kernel, the following vulnerability has been resolved: mmc: via-sdmmc: fix return value check     of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, it will lead two issues:
    1. The memory that allocated in mmc_alloc_host() is leaked. 2. In the remove() path, mmc_remove_host()     will be called to delete device, but it's not added yet, it will lead a kernel crash because of null-ptr-     deref in device_del(). Fix this by checking the return value and goto error path which will call     mmc_free_host(). (CVE-2022-50846)

  - In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Fix memory leak in     uvc_gpio_parse Previously the unit buffer was allocated before checking the IRQ for privacy GPIO. In case     of error, the unit buffer was leaked. Allocate the unit buffer after the IRQ to avoid it. Addresses-     Coverity-ID: 1474639 (Resource leak) (CVE-2022-50882)

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

This     patch initializes the 8 byte CAN header with zero. (CVE-2022-49845)

  - In the Linux kernel, the following vulnerability has been resolved: misc: tifm: fix possible memory leak     in tifm_7xx1_switch_media() If device_register() returns error in tifm_7xx1_switch_media(), name of     kobject which is allocated in dev_set_name() called in device_add() is leaked.

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8668-1 advisory.

    Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly     validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use     this to construct a malicious NTFS image that, when mounted and operated on, could expose sensitive     information (kernel memory). (CVE-2023-45896)

    It was discovered that some AMD processors did not properly clear data in the floating point divider unit     during speculative execution. A local attacker could use this to expose sensitive information.
    (CVE-2025-54505)

    It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the     operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a     higher privilege level, resulting in privilege escalation. (CVE-2025-54518)
