CVE-2022-20313

Local privilege escalation via Bluetooth bounds failure

Published Aug 11, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Android 13 Bluetooth allows local users with System execution privileges to escalate privileges without interaction. Bluetooth processing fails to bounds-check an undisclosed input before writing beyond its destination buffer; Google has not published the affected function or data path. Exploitation requires existing System execution privileges and Bluetooth reachability, and the resulting memory corruption enables local privilege elevation.
