AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel by adding a guard to ensure interrupts are only unmasked when the ACTIVE state is true. Users should update to a kernel version that includes this fix. The affected versions listed should be upgraded or patched accordingly. No additional mitigation actions are required beyond applying the official fix.
Description
CVE-2026-99005 is a vulnerability in the Linux kernel's drm/i915 graphics driver related to unmasking interrupts when the ACTIVE state is false. A race condition can cause interrupts to be unmasked after the graphics technology (GT) has been parked and the runtime power management wakelock dropped, leading to kernel tainting due to hardware access without a held wakelock. The issue arises from a small race window between checking the ACTIVE state and queuing work that handles power management interrupts. The fix ensures interrupts are only unmasked when the ACTIVE state is true, preventing this improper access.
