Descriptions

The Bluetooth Low Energy (BLE) stack implementation on Cypress PSoC 4 through 3.62 devices 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 dispositivos Cypress PSoC 4 versiones hasta 3.62, 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, causar un comportamiento anómalo en la máquina de estado BLE o desencadenar un desbordamiento del búfer por medio de una trama BLE Link Layer diseñada.
