Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amdgpu: prevent immediate PASID reuse case<br />
<br />
PASID resue could cause interrupt issue when process<br />
immediately runs into hw state left by previous<br />
process exited with the same PASID, it&#39;s possible that<br />
page faults are still pending in the IH ring buffer when<br />
the process exits and frees up its PASID. To prevent the<br />
case, it uses idr cyclic allocator same as kernel pid&#39;s.<br />
<br />
