CVE-2022-20258

Local privilege escalation via mitigation misconfiguration

Published Aug 11, 2022 · Updated Aug 3, 2024

Privilege escalation in Android 13 Bluetooth allows local users to gain elevated privileges by bypassing compiler exploit mitigations. A Bluetooth build configuration leaves compiler exploit mitigations bypassable; Google has not disclosed the specific setting or code path. No user interaction is required, but exploitation requires prior local low-privileged execution.
