Local privilege escalation via use-after-free
Published Nov 4, 2025 · Updated Nov 4, 2025
Use-after-free in MediaTek APUSYS on Android 13.0, 14.0, and 15.0 allows local users with System privilege to escalate privileges. MediaTek identifies freed-memory reuse in APUSYS as the cause of memory corruption but has not disclosed the affected function, object, or triggering input. Exploitation requires existing System privilege and no user interaction, and the reported consequence is local privilege escalation.
