CVE-2026-22167GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory
High 7.8
In plain English
A high-severity memory corruption in Graphics DDK from Imagination Technologies. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 5% of all known vulnerabilities).
Official description
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.
