medium Tenable Cloud Security Plugin ID 460564

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: fix kthread lifetime race
 between self-exit and external-stop RSI driver use both self-exit(kthread_complete_and_exit) and external-
 stop (kthread_stop) when killing a kthread. Generally, kthread_stop() is called first, and in this case,
 no particular issues occur. However, in rare instances where kthread_complete_and_exit() is called first
 and then kthread_stop() is called, a UAF occurs because the kthread object, which has already exited and
 been freed, is accessed again. Therefore, to prevent this with minimal modification, you must remove
 kthread_stop() and change the code to wait until the self-exit operation is completed. (CVE-2026-46187)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
