CVE-2019-17060: Bluetooth®Smart/Bluetooth Low Energy | NXP Semiconductors
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.
Our Bluetooth Smart (Bluetooth Low Energy) solutions include highly integrated SoCs with plentiful Flash and SRAM memory utilizing Arm® Cortex®-M cores. These products enable ultra-low-power operation without compromising radio performance. In addition to providing complete SoCs, a host Bluetooth Low Energy stack is provided, as well as several GATT profiles and services.
The recently announced MCX W wireless MCUs improve battery life, reduce external components and support the latest Bluetooth standards. Learn more about the MCX portfolio.
