The Bluetooth Low Energy peripheral implementation on Texas Instruments SIMPLELINK-CC2640R2-SDK through 3.30.00.20 and BLE-STACK through 1.5.0 before Q4 2019 for CC2640R2 and CC2540/1 devices does not properly restrict the advertisement connection request packet on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet.
La implementación periférica de Bluetooth Low Energy en Texas Instruments SIMPLELINK-CC2640R2-SDK versiones hasta 3.30.00.20 y BLE-STACK versiones hasta 1.5.0 anteriores a Q4 2019 para dispositivos CC2640R2 y CC2540/1 no restringe apropiadamente el paquete de petición de conexión de publicidad en la recepción, permitiendo a atacantes dentro del radio de alcance para causar una denegación de servicio (bloqueo) por medio de un paquete diseñado.
