CVE-2022-46891Network attack vector

Authenticated freed-memory access via improper GPU processing

Published Jan 17, 2023 · Updated Nov 27, 2024

Use-after-free in the Arm Mali GPU Kernel Driver allows remote authenticated users to access freed memory through improper GPU processing operations. The public record does not identify the affected function or the lifetime error that leaves freed driver memory reachable during GPU processing. A low-privilege account is sufficient, and the documented consequence is access to stale memory rather than confirmed code execution.
