    "title": "drm/i915/gt: Unmask interrupts only when ACTIVE is true",
    "summary": "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: -> rps_disable_interrupts() -> cancel_work_sync(rps->work) -> rps_reset_interrupts() [rps->pm_iir = 0] WITHOUT INTERRUPTS (TIMER mode): -> rps_stop_timer() -> cancel_work_sync(rps->work) 2) live_rc6_ctx_wa() -> intel_gt_wait_for_idle() -> intel_gt_retire_requests_timeout() -> dma_fence_wait_timeout() -> ops->wait() [i915_fence_wait()] -> i915_request_wait_timeout() -> intel_rps_boost() -> intel_rps_is_active() [check ACTIVE] [OPEN RACE WINDOW] -> queue_work(rps->work) -> retire_requests() -> i915_request_retire() -> intel_rps_dec_waiters() [from 1 to 0] If ASYNC1 and ASYNC2 would execute during [OPEN RACE WINDOW], then: 3",
