I’m skeptical of that claim. The key material presumably is inaccessible even to the OS without the passcode.
If someone drops 5 confirmed ring 0 exploits/bypasses within 3 months and claims that they got a 6th one... why on earth would you doubt that the 6th one suddenly is fake?
Do you know how hard discovering even one of those is? And how many months of work it takes?

That's the thing, we don't actually know how involved the PIN is in relation to the key... it might be completely separate (and hence bypassable).
Similarly I also wonder if password-based pre-boot auth is affected.
