BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GETFOLDERITEMS 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 attrid parameter to cause crashes and corrupt attribute bitmap state.

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

BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller LISTPLAYERAPPLICATIONSETTINGATTRIBUTES and LISTPLAYERAPPLICATIONSETTINGVALUES handlers that allows attackers to read beyond buffer boundaries. A nearby attacker with a paired Bluetooth Classic connection can send a specially crafted VENDORDEPENDENT response with an attacker-controlled count value to trigger an out-of-bounds read from the L2CAP receive buffer, potentially causing a crash on resource-constrained devices.
