CVE-2025-38369 is a workqueue lifecycle flaw in the Linux kernel's IDXD DMA engine driver. Running IDXD workloads inside a container with the host device directory mounted can trigger a kernel call trace or panic when the container's parent process terminates. Under certain Docker configurations, mount replicas are not properly propagated back to the original mount point. During user-driver detachment, cleanup attempts to complete pending work through destroy_workqueue() despite the workqueue having already been destroyed. The fix checks whether wq->wq exists and skips draining when it does not.

A Linux kernel dmaengine IDXD driver flaw involving use of a workqueue after its destruction. Under certain container mount configurations, terminating the container's parent process can cause a call trace or kernel panic. The fix checks whether the workqueue still exists before attempting to drain it. The plugin reports a CVSS v3 base score of 7.8 and recommends updating Echo linux packages to version 6.12.37-1 or later.
