Local privilege escalation via Bluetooth out-of-bounds write
Published Oct 30, 2023 · Updated Aug 2, 2024
An out-of-bounds write in Android 14 Bluetooth allows local users with System execution privileges to escalate privileges without interaction. The Bluetooth component insufficiently validates an unspecified input before a write proceeds beyond the intended buffer bounds. Exploitation requires existing System execution privileges, and Google has not disclosed the affected function, input format, or resulting privilege boundary.
