How Researchers Bypassed Apple's M5 Memory Integrity Enforcement in Five Days

Summary

A detailed technical analysis of how security researchers (a three-person team with AI assistance) bypassed Apple's new Memory Integrity Enforcement (MIE) security system on the M5 chip in just five days. The article explains MIE's sophisticated design—hardware memory tagging, locked read-only kernel zones, and a privileged monitor—and the two bugs and clever exploit technique used to defeat it. It provides a rundown accessible to technical readers without requiring a PhD, covering implications for both defenders and exploit writers.
