here at the TelcoSecDay of I'm learning that in 2019, SS7 firewall/IDS products use a ten year old kernel (2.6.32) and are vulnerable to IP fragmentation bypass which are at least 20 years old. Is that the state of cellular security, OMFG!

IIRC AVM also still ships 2.6 with their FRITZ!Box Routers. At least they did not so many moons ago. Please correct me if I'm wrong.
