CVE-2026-22167 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour. This attack can lead the GPU to perform write operations on restricted internal GPU buffers that can lead to a second order affect of corrupted arbitrary physical memory.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
