Description

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

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
