CVE-2026-53201: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.1% chance of exploitation in the next 30 days.

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