Local memory overwrite via constant-pattern out-of-bounds write
Published Dec 4, 2023 · Updated Aug 28, 2024
Out-of-bounds write in Arm Mali GPU userspace drivers allows local users to overwrite limited unallocated memory with a constant pattern. Arm discloses that the userspace driver writes beyond its allocated memory but does not identify the affected routine or triggering input. A non-privileged local account is required; the published record does not establish control of the written bytes beyond the constant pattern.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
