Description OSIDB Bzimport 2026-09-25 13:39:03 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Recover HW before retire hung submit

During recovery, it is not safe to retire the hung submit before we
recover the GPU. Retiring the submit triggers BO free and that can
result in GPU pagefaults since the GPU may be actively accessing those
BOs.

To fix this, retire the submits after gpu recovery is complete in
recover_worker().
