AI-suggested
A patch is available and has been released in linux-hwe-edge kernel versions 7.0.0-31.31 and later. Users should upgrade to these fixed versions to remediate the vulnerability. The vendor advisory confirms the fix and recommends updating to the patched kernel releases.
Description
A vulnerability in the Linux kernel related to the drm/xe GPU driver was resolved by reverting an optimization that skipped exec queue schedule toggling during suspend. This optimization bypassed the GuC suspend process, causing missed TLB invalidations and potential page faults during userptr invalidation tests in certain VM modes. The fix restores unconditional schedule toggling on suspend to ensure proper TLB flushes. The vulnerability affects specific linux-hwe-edge kernel versions and has been fixed in later releases.
