BlueBorne is a recently published attack vector that exploits security gaps in Bluetooth classic connections and can be used to execute malicious code on affected devices. More details about the specific vulnerabilities can be found below.
The BlueBorne attack vectors exploits security gaps in the host Bluetooth stack implementation and is not related in any way to the ATWILC3000 firmware or driver implementation.
BlueBorne targets vulnerabilities in Android and Linux BlueDroid and BlueZ stack implementation which allow Remote Code Execution (RCE) on the host within high privileged process and/or kernel space. The BlueBorne attack vector exploits the following eight vulnerabilities in the host Bluetooth stack implementation and is not related in any way to the Microchip Bluetooth device firmware or driver implementation.
