Descriptions

The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service (crash) in ESP32 by flooding the target device with LMP Feature Response data.

Una implementación de Bluetooth Classic en Espressif ESP-IDF versión 4.4 y anteriores, no maneja apropiadamente la recepción de respuestas LMP continuas no solicitadas, permitiendo a atacantes en el rango de radio desencadenar una denegación de servicio (caída) en ESP32 inundando el dispositivo de destino con datos de respuesta de características LMP
