Title
BlueKitchen BTstack < 1.8.1 AVRCP Browsing Target GET_FOLDER_ITEMS Handler OOB Read / Undefined Behavior
Summary
BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GET_FOLDER_ITEMS handler that fails to validate packet boundaries and attribute count data. An attacker with a paired Bluetooth Classic connection can exploit insufficient bounds checking on the attr_id parameter to cause crashes and corrupt attribute bitmap state.
