- Summary
- CVE-2025-38515 affecting package kernel for versions less than 6.6.104.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/sched: Increment job count before swapping tail spsc queue
A small race exists between spscqueuepush and the run-job worker, in which spscqueuepush may return not-first while the run-job worker has already idled due to the job count being zero. If this race occurs, job scheduling stops, leading to hangs while waiting on the job’s DMA fences.
Seal this race by incrementing the job count before appending to the SPSC queue.
This race was observed on a drm-tip 6.16-rc1 build with the Xe driver in an SVM test case.
