Descriptions
The Bluetooth Classic implementation on AB32VG1 devices does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service (either restart or deadlock the device) by flooding a device with LMP_AU_rand data.
La implementación de Bluetooth Classic en los dispositivos AB32VG1, 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 (reiniciar o bloquear el dispositivo) inundando un dispositivo con datos LMP_AU_rand
