CVE-2022-20333

Bluetooth process crash via missing null check

Published Aug 11, 2022 · Updated Aug 3, 2024

Null pointer dereference in Android 13 Bluetooth allows physically proximate attackers to crash a Bluetooth process without authentication. The Android record identifies the Bluetooth component and a missing null check but does not disclose the function, input field, or dereference path. Bluetooth reachability is required, but no privileges or user interaction are needed; the reported consequence is a process crash, not code execution or data access.
