Descriptions

The Bluetooth Low Energy (BLE) stack implementation on the NXP KW41Z (based on the MCUXpresso SDK with Bluetooth Low Energy Driver 2.2.1 and earlier) does not properly restrict the BLE Link Layer header and executes certain memory contents upon receiving a packet with a Link Layer ID (LLID) equal to zero. This allows attackers within radio range to cause deadlocks, cause anomalous behavior in the BLE state machine, or trigger a buffer overflow via a crafted BLE Link Layer frame.

La implementación de la pila de Bluetooth Low Energy (BLE) en el NXP KW41Z (basada en MCUXpresso SDK con Bluetooth Low Energy Driver versión 2.2.1 y anteriores), no restringe apropiadamente el encabezado BLE Link Layer y ejecuta determinados contenidos de memoria tras recibir un paquete con un Link Layer ID (LLID) igual a cero. Esto permite a atacantes dentro del radio de alcance causar puntos muertos, un comportamiento anómalo en la máquina de estado BLE o desencadenar un desbordamiento del búfer por medio de una trama BLE Link Layer diseñada.
