Descriptions
The Bluetooth Classic implementation on Actions ATS2815 chipsets does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service and shutdown of a device by flooding the target device with LMP_features_res packets.
La implementación de Bluetooth Classic en los conjuntos de chips Actions ATS2815 no maneja apropiadamente la recepción de respuestas LMP continuas no solicitadas, que permite a atacantes en el rango de radio desencadenar una denegación de servicio y el apagado de un dispositivo mediante la inundación del dispositivo de destino con paquetes LMP_features_res
