There have been MANY such attacks against the iPhone (and every other device), most of them against the biometrics mechanisms, which tend to be pretty weak as a matter of first principles. Add to that the persistent hints/rumors/claims of gray market unlock/rooting kits available to large entities. Phones just aren't that secure, though they're much more so than they were a decade ago. Security vs. physical access is an extremely hard nut to crack, it's only been in the last few years that we genuinely thought it was even possible.
Fooling a biometric sensor is precisely a lock screen bypass, that's what the biometrics are for. By that logic the linked bug was "fooling the SIM security layer" and not a "lock screen bypass". Don't play that game, it's bad logic and bad security practice.
But it’s a fundamentally different type of security bug: these biometrics bypasses require knowing something about the user (lift a fingerprint, picture of a face, etc).
I see this as a different class: I can grab an unknown person’s Pixel they left in a coffee shop and get into it.
Zerodium brokers sales of iOS FCP Zero Click for $2m. I expect they sell to people like Cellebrite who can make a profit selling expensive unlocks and keeping the vuln secret.
Has iOS had a Lock Screen bypass in recent history?
