The flaw lies in the Linux kernel’s DRM scheduler for Imagination PowerVR GPUs. When a geometry job with an attached fragment job is prepared, the scheduler incorrectly checks for space in the geometry job’s command buffer instead of the fragment job’s buffer. This misallocation can trigger job timeouts, cause kernel warning messages, and ultimately lead to instability or crashes that disrupt GPU‑dependent processes. The issue is also categorized under CWE‑1285, CWE‑665, and CWE‑400, reflecting improper resource management and control flow checks.

All Linux kernel builds that compile the Imagination PowerVR DRM driver are susceptible, including current development releases such as kernel 7.0.0‑rc series and earlier kernels that contain the unpatched driver code.

The EPSS score is below 1 % and the vulnerability is not listed in the CISA KEV catalog, indicating a low probability of extensive exploitation. Based on the description, it is inferred that an attacker with local or privileged access who can submit GPU jobs could trigger the bug, leading to repeated warnings, kernel instability, and a denial of service to GPU‑dependent workloads.
