Answer in brief
CVE-2026-45196 records a High severity (CVSS 7.8) vulnerability in GPU DDK - Arbitrary GPU register write in rgxfw_hwperf_hw due to unsanitized pointers from host kernel. 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 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
