Natalie bricked a room full of Apple engineer's phones when they asked her to help repro this!
Answer a FaceTime call from an attacker, and remote iOS kernel memory corruption....https://twitter.com/natashenka/status/1059589940240048128 …
It's a remote kernel memory corruption, it doesn't get any more serious than that. A real attack isn't going to have any visible effect, you're just going to be compromised. The "bricked" part was just a fun anecdote.

It's not hard to brick a phone if you have the right bug. Basically just trigger a fatal crash via a message that is parsed when the system boots up => welcome to the bootloop. Android has (had) that kind of thing too that could be triggered via Signal:https://youtu.be/2n9HmllVftA?t=1474 …

It is still a much rarer occurence than a kernel panic. And even when it is parsed when the system boots up, then that does not mean that you cannot erase that memory. Bricked means dead beyond hope.
