NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-devel-matched package and not the kernel-zfcpdump-devel-matched package as distributed by AlmaLinux.

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: Check availability of workqueue allocated by idxd wq driver before using

Running IDXD workloads in a container with the /dev directory mounted can trigger a call trace or even a kernel panic when the parent process of the container is terminated.

This issue occurs because, under certain configurations, Docker does not properly propagate the mount replica back to the original mount point.

In this case, when the user driver detaches, the WQ is destroyed but it still calls destroy_workqueue() attempting to completes all pending work. It's necessary to check wq->wq and skip the drain if it no longer exists.
