Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/xe/vm: Fix BO prefetch with CONSULT_MEM_ADVISE_PREF_LOC<br />
<br />
When prefetch region is DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC for a BO VMA,<br />
the code used it as an index into region_to_mem_type[], causing an<br />
out-of-bounds access since the value is -1.<br />
<br />
Resolve the preferred location for BO VMAs directly: local VRAM on dGFX<br />
(using the BO&#39;s tile placement) or system memory on iGPU.<br />
<br />
Discovered using AI-assisted static analysis confirmed by Intel Product<br />
Security.<br />
<br />
v2:<br />
-Fix null dereference<br />
