Answer in brief
CVE-2026-41156 records a High severity (CVSS 7.7) vulnerability in GPU DDK - kernel<->fw CCB contains SYNC_PRIMITIVE_BLOCK firmware address without holding reference. The current sources do not mark it as known exploited. The current feed maps Imagination Technologies/Graphics DDK (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.7. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources creating a write use after free scenario. A shared resource (memory page) managed by a CPU thread of control (driver) and accessed by a GPU thread of control (Firmware) can cause a write UAF when the CPU thread frees the resource before the GPU FW has finished accessing it.
