Descriptions
The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of multiple LMP IO Capability Request packets during the pairing process, allowing attackers in radio range to trigger memory corruption (and consequently a crash) in ESP32 via a replayed (duplicated) LMP packet.
Una implementación de Bluetooth Classic en Espressif ESP-IDF versiones 4.4 y anteriores, no maneja apropiadamente la recepción de múltiples paquetes de petición de capacidad LMP IO durante el proceso de emparejamiento, permitiendo a atacantes en el rango de radio desencadenar una corrupción de la memoria (y en consecuencia un bloqueo) en el ESP32 por medio de un paquete LMP reproducido (duplicado)
