Technical 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.
