In short

A local user can access memory that was already freed on a Mali GPU, potentially exposing sensitive data or causing system instability. This happens because the GPU driver doesn't properly manage memory cleanup.

Technical detail

A use-after-free vulnerability (CWE-416) in the Mali GPU kernel driver allows a local unprivileged attacker to perform improper GPU memory operations and access freed memory. No special privileges are required; the attack vector is local and exploits insufficient memory state management in the GPU driver, potentially leading to information disclosure or denial of service.
