CVE-2026-22167: GPU Memory Corruption in Imagination DDK 1.18–26.1

The core impact of CVE-2026-22167 is the potential for arbitrary memory corruption. By exploiting the improper GPU system calls, an attacker can force the GPU to write to memory pages outside of its allocated space, including those used by the kernel and other drivers. This corruption can lead to a wide range of consequences, including system crashes, denial of service, and potentially even arbitrary code execution. The second-order effect of corrupted arbitrary physical memory is particularly concerning, as it can destabilize the entire system. This vulnerability shares similarities with other GPU-related memory corruption exploits, highlighting the importance of robust memory management within the driver.

The primary mitigation for CVE-2026-22167 is to upgrade to a patched version of the Imagination Technologies Graphics DDK. As a workaround, restrict access to GPU system calls to only trusted processes. Implement stricter input validation for any data passed to the GPU driver. Consider using memory protection mechanisms, such as address space layout randomization (ASLR), to make it more difficult for attackers to predict the location of vulnerable memory pages. Monitor system logs for unusual GPU activity or memory errors. After upgrading, confirm the fix by running memory integrity tests and observing GPU behavior under stress.
