Description

A race condition vulnerability exists in Arm Ltd's Bifrost, Valhall, and 5th Gen GPU Kernel Drivers. This flaw allows a local non-privileged user process to improperly handle GPU memory operations, potentially causing denial of service or disclosure of sensitive information. The affected versions span multiple release ranges for each GPU driver architecture.
