Descriptions

The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets.

La implementación del controlador Bluetooth Low Energy (BLE) en Espressif ESP-IDF versiones 4.0 hasta 4.2 (para dispositivos ESP32) devuelve el número errado de paquetes BLE completados y desencadena una aserción alcanzable en la pila del host cuando está recibiendo un paquete con un fallo de MIC. Un atacante dentro del radio de alcance puede desencadenar silenciosamente la aserción (que deshabilita la pila BLE del objetivo) al enviar una secuencia de paquetes BLE diseñada
