CVE-2025-38515

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: A race condition exists between the spsc queue push function and the run-job worker, potentially causing job scheduling to halt and leading to hangs while waiting on DMA fences. This occurs when spsc queue push returns not-first while the run-job worker has idled due to a zero job count. The issue was observed on a drm-tip 6.16-rc1 build with the Xe driver in an SVM test case.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
