In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: drop redundant sched job cleanup when cs is aborted

Once command submission failed due to userptr invalidation in
amdgpu_cs_submit, legacy code will perform cleanup of scheduler
job. However, it's not needed at all, as former commit has integrated
job cleanup stuff into amdgpu_job_free. Otherwise, because of double
free, a NULL pointer dereference will occur in such scenario.
