Arm Mali GPU Userspace Drivers Buffer Overflow Vulnerability

A buffer overflow vulnerability has been identified in the Arm Mali GPU Userspace Drivers for Bifrost, Valhall, and 5th Gen GPU Architecture. This vulnerability allows a non-privileged user process to perform valid GPU processing operations, including through WebGL or WebGPU, and access memory outside of buffer bounds. The issue is present in multiple versions across the different GPU architectures.

Impact

Exploitation of this vulnerability leads to out-of-bounds memory access, which can potentially be exploited to execute arbitrary code or cause a denial-of-service condition.

Remediation

Users are advised to upgrade to the latest versions of the Arm Mali GPU Userspace Drivers. The fixed versions are included in the official Arm Mali GPU Driver Security Bulletin.
