Vulnerability from github – Published: 2026-09-25 15:31 – Updated: 2026-09-25 15:31

Details

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().
