CVE-2026-53201

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend"<br /> <br /> This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.<br /> <br /> The idle-skip optimization bypasses GuC suspend, so the GPU may not<br /> perform the context switch that flushes TLB entries for invalidated<br /> userptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB<br /> invalidation and page faults during userptr invalidation tests.<br /> <br /> Restore unconditional schedule toggling on suspend so the context-switch<br /> TLB flush is always performed.<br /> <br /> This optimization will be reintroduced with a fix that does not skip<br /> suspend in LR/preempt-fence VM mode.<br /> <br /> (cherry picked from commit 6a1e7934d9a6cf46aecae00a99c2603d1295e170)
