The Imagination driver in the Linux kernel contains a race condition that allows the runtime PM suspend callback to initiate a suspend while an IRQ handler for the GPU is still executing on another CPU core. This race can cause the IRQ handler to access GPU registers after the GPU has been suspended, resulting in an asynchronous SError interrupt that triggers a kernel panic. The weakness is a classic timing race (CWE‑364) between power management and interrupt handling, which can lead to a fatal system crash.

All Linux kernel builds that include the unpatched Imagination GPU driver are affected, including the example crash observed on a Texas Instruments AM68 SK (RISC‑V) platform. The CPE string indicates the vulnerability applies broadly to Linux kernel releases. Specific version numbers are not listed in the provided data, so any kernel prior to the pending patch that contains the driver code is at risk.

The EPSS score is below 1 % and the vulnerability is not in the CISA KEV catalog, implying a low short‑term exploitation probability. However, the impact of the bug—immediate kernel panic—makes it severe if triggered. The most likely trigger is a normal suspend/resume event or system power down, so the risk is high for systems performing such power transitions rather than a classic remote exploit. No public exploit is known, but the crash can be induced by typical power management activity.
