CVE-2026-99005CVE-2026-99005

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Unmask interrupts only when ACTIVE is true There is a small race window between intel_rps_boost() reading a stale ACTIVE state and queuing rps->work, where ACTIVE may be changed via asynchronous calls triggered by wakeref drop. This means that rps_work() could be triggered after the GT has been parked, so unmasking RPS PM interrupts would happen without holding PM wakelock. This sequence of events may be observed during live_rc6_ctx_wa() selftest: 1) live_rc6_ctx_wa() -> intel_engine_pm_put() -> wakeref_put() ASYNC1) wakeref_put() callback -> __engine_park() -> intel_gt_pm_put_async() -> intel_gt_pm_put_async_untracked() -> intel_wakeref_put_async() ASYNC2) wakeref_put_async() callback -> __gt_park() -> intel_rps_park() -> intel_rps_clear_active() [clear ACTIVE] WITH INTERRUPTS:
