BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller GET_PLAYER_APPLICATION_SETTING_ATTRIBUTE_TEXT and GET_PLAYER_APPLICATION_SETTING_VALUE_TEXT handlers that allows nearby attackers to read beyond packet boundaries. Attackers can establish a paired Bluetooth Classic connection and send specially crafted VENDOR_DEPENDENT responses to trigger out-of-bounds reads, causing information disclosure and potential crashes on affected devices.
