Remote information disclosure via overflowing AVRCP length
Published Oct 11, 2022 · Updated Aug 3, 2024
Out-of-bounds read in Android 10 through 13 allows remote attackers to disclose process memory through a crafted Bluetooth AVRCP vendor response. The parser trusts a vendor-supplied string length whose arithmetic can overflow, then reads past the response buffer before verifying that enough bytes remain. A Bluetooth peer can trigger the flaw without privileges or user action, exposing memory contents without modifying data or interrupting the device.
