CVE-2026-23469 is a race condition in the Linux kernel's drm/imagination GPU driver. During runtime power-management suspend, the suspend callback did not ensure that an IRQ handler executing on another CPU had completed before powering down the GPU. As a result, the threaded interrupt handler could continue running while the GPU was already suspended and attempt to access GPU registers, leading to faults and kernel crashes. The upstream fix adds synchronize_irq() in the runtime PM power-off/suspend path to wait for in-flight interrupt handlers to finish, and removes runtime PM resume/put calls from the threaded IRQ handler to avoid an associated deadlock with the device power lock.
