Local kernel memory access via stale GPU translations
Published Jun 25, 2026 · Updated Jun 25, 2026
Improper GPU TLB invalidation in Linux Kernel 7.0 through 7.0.12 allows local users to access reused memory via stale translations. The drm/xe idle-queue suspend path skips the GuC context switch that flushes GPU TLB entries after invalidated userptr pages are reused. Access to the Xe DRM render node and LR/preempt-fence VM mode lets stale translations read or corrupt reused pages and trigger GPU faults, hangs, or resets.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
