Race condition in Linux kernel - CVE-2026-99005
Published: October 23, 2026
Vulnerability details
The vulnerability allows a local user to trigger a kernel warning and taint the kernel.
The vulnerability exists due to a race condition in the i915 driver's RPS work handling when scheduling work concurrently with asynchronous GT parking. A local user can trigger this race so that rps_work() unmasks power-management interrupts after the GT has been parked, causing hardware register access without a runtime power-management wakelock and triggering a kernel warning that taints the kernel.
