Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: prevent immediate PASID reuse case
PASID resue could cause interrupt issue when process
immediately runs into hw state left by previous
process exited with the same PASID, it's possible that
page faults are still pending in the IH ring buffer when
the process exits and frees up its PASID. To prevent the
case, it uses idr cyclic allocator same as kernel pid's.
