Arm Mali Valhall GPU Kernel Driver and 5th Gen GPU Architecture Kernel Driver Use-After-Free Vulnerability

A use-after-free vulnerability has been identified in the Arm Mali Valhall GPU Kernel Driver and the Arm 5th Gen GPU Architecture Kernel Driver, both allowing local non-privileged user processes to access already freed memory. This vulnerability arises from improper GPU memory processing operations, potentially leading to unauthorized access to sensitive data or causing memory corruption.

Impact

Exploitation of this vulnerability could allow a local non-privileged user process to access already freed memory, potentially leading to memory corruption or unauthorized data access.

Remediation

Users are advised to upgrade to Valhall GPU Kernel Driver versions r54p2 or r55p0, or to Arm 5th Gen GPU Architecture Kernel Driver versions r54p2 or r55p0.
