PublishedIn the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: Fix BO prefetch with CONSULT_MEM_ADVISE_PREF_LOC When prefetch region is DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC for a BO VMA, the code used it as an index into region_to_mem_type[], causing an out-of-bounds access since the value is -1.
