LPE exploit demoed on iPhone 12 with iOS 14.1, just days after recent jailbreak teaser

Progress appears to be getting made on a feat showed off just this past weekend in which security researcher @pattern_F_ with the Ant Security Lab demonstrated what appeared to be a successful jailbreak attempt on an iPhone 11 running iOS 14.0.

Late last night, the security researcher took to Twitter yet again, this time to demonstrate a local privilege escalation (LPE) exploit on an iPhone 12 running iOS 14.1. The first two things that should jump out at you there are that the iPhone is one model year newer and that the firmware it’s running is one iteration newer.
