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.
