CVE-2026-23469

A flaw was found in the Linux kernel's drm/imagination driver. This vulnerability arises from a race condition where the runtime Power Management (PM) suspend callback does not wait for the Interrupt Request (IRQ) handler to complete before suspending the Graphics Processing Unit (GPU). This timing issue can lead to the IRQ handler attempting to access GPU registers while the GPU is suspended, resulting in a kernel crash and a Denial of Service (DoS) for the system.
