Race Condition Vulnerability in GPU System Calls Affecting Imagination Technologies Software

CVE-2026-15466

What is CVE-2026-15466?

A race condition vulnerability exists in the GPU system calls of Imagination Technologies software, which is run by non-privileged users. This flaw can lead to improper management of hardware performance counters, resulting in a critical failure during the destruction process. Specifically, due to non-atomic reference counter decrements, there's potential for other code paths to access freed objects, enabling unauthorized read and write operations within kernel heap memory. This can compromise the integrity and security of the system, highlighting the importance of addressing such vulnerabilities promptly.
