CVE-2018-9413

Remote code execution via unchecked AVRCP attribute count

Published Dec 2, 2024 · Updated Dec 3, 2024

Out-of-bounds write in Android 7 through 8.1 allows remote attackers to execute code through a crafted Bluetooth AVRCP response. The AVRCP parser trusts num_attr in an application-setting-change notification and writes that many attribute pairs into fixed-size arrays. Exploitation requires a Bluetooth peer and user interaction; successful corruption executes code with the Bluetooth process privileges.
