This is not a remote exploit. It's not even a backdoor. It's just a bunch of undocumented interface commands that allow access to things like memory. To exploit any of this you need an attacker have physical access or get to run privileged software on the device. In both cases you'd already be totally screwed anyway. This is a clickbait nothingburger and that's the reason why it was presented at a random local conference. An actual backdoor that infects billions of wireless devices would have easily earned you a top presenter spot at a highly prestigious conference.
