What fixes it

  • 2f021d93f15829ba052ff22bc40df0ec3ae7c7abLinuxCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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().
