high Tenable Cloud Security Plugin ID 454635

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: workqueue: Put the pwq after detaching
the rescuer from the pool The commit 68f83057b913("workqueue: Reap workers via kthread_stop() and remove
detach_completion") adds code to reap the normal workers but mistakenly does not handle the rescuer and
also removes the code waiting for the rescuer in put_unbound_pool(), which caused a use-after-free bug
reported by Cheung Wall. To avoid the use-after-free bug, the pool’s reference must be held until the
detachment is complete. Therefore, move the code that puts the pwq after detaching the rescuer from the
pool. (CVE-2025-21786)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 19165.0.0 or later.
