Pardon MIE? Sat May 23, 2026Pardon MIE? Sat May 23, 2026Apple s Memory Integrity Enforcement is no joke. Five years of design, brand-new M5 silicon, hardware memory tagging on the kernel heap, hardware-locked read-only zones for the kernel s crown jewels, and a privileged monitor sitting above the kernel that refuses every unauthorised page-table change. It s the most serious kernel memory-safety stack any consumer OS has shipped. And it still got bypassed. A three-person shop with an AI sidekick walked through it in five days, with two bugs and a clever idea. Here s my rundown of how they achieved it, no PhD required.
Almost every your iPhone got hacked story you ve ever read comes back to the same root cause: a memory bug. A pointer that pointed at the wrong thing. A buffer that wrote one byte too many. A struct that got reused after it was supposed to be freed.
It s not the user clicking a sketchy link. It s not a stolen password. It s the kernel reading from a piece of memory and trusting it just a little too much.
