Technical description

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)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
