CVE-2018-9418

Remote code execution via unchecked AVRCP attribute count

Published Dec 2, 2024 · Updated Dec 3, 2024

Stack buffer overflow in the Bluetooth system component in Google Android 7.0, 7.1.1, 7.1.2, 8.0, and 8.1 allows remote attackers to execute code. The handle_app_cur_val_response function trusts an AVRCP response count and copies that many attribute IDs and values into fixed-size stack arrays. A Bluetooth peer can trigger the overwrite without authentication or user interaction, gaining code execution in the Bluetooth process.
