Title
drm/amdgpu: fix a job->pasid access race in gpu recovery
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix a job->pasid access race in gpu recovery Avoid a possible UAF in GPU recovery due to a race between the sched timeout callback and the tdr work queue. The gpu recovery function calls drm_sched_stop() and later drm_sched_start(). drm_sched_start() restarts the tdr queue which will eventually free the job. If the tdr queue frees the job before time out callback completes, the job will be freed and we'll get a UAF when accessing the pasid. Cache it early to avoid the UAF.
