Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dmaengine: idxd: Check availability of workqueue allocated by idxd wq driver before using<br /> <br /> Running IDXD workloads in a container with the /dev directory mounted can<br /> trigger a call trace or even a kernel panic when the parent process of the<br /> container is terminated.<br /> <br /> This issue occurs because, under certain configurations, Docker does not<br /> properly propagate the mount replica back to the original mount point.<br /> <br /> In this case, when the user driver detaches, the WQ is destroyed but it<br /> still calls destroy_workqueue() attempting to completes all pending work.<br /> It&amp;#39;s necessary to check wq-&gt;wq and skip the drain if it no longer exists.
