Answer in brief
CVE-2026-45203 records a High severity (CVSS 7.8) vulnerability in GPU DDK - rgxfw_hwperf_ufo() re-reads psCmdHeader->ui32CmdSize after initial check, TOCTOU. 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.

Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory write outside the permitted range of memory for the host kernel. A TOCTOU bug existed where a malicious driver could modify values in memory after firmware validation but before use.
