Local privilege escalation via WLAN out-of-bounds write
Published May 6, 2024 · Updated Mar 28, 2025
An out-of-bounds write in the MediaTek WLAN service on Android 13.0 and 14.0 allows local users to escalate privileges. The service improperly validates input before a write exceeds its destination buffer, while MediaTek has not disclosed the affected function or field. Exploitation requires local code execution but no additional execution privileges or user interaction, and successful memory corruption grants higher privileges.
