Local privilege escalation via missing Bluetooth authorization
Published Aug 11, 2022 · Updated Aug 3, 2024
Missing authorization in Android 13 Bluetooth allows local users to connect or disconnect devices without user awareness. An undisclosed Bluetooth code path processes a requested connection-state change without first checking the caller's permission. Exploitation requires user-level execution on the affected device but no user interaction, and its bounded effect is unauthorized control of Bluetooth connections.
