There's a stat buried in a recent security disclosure that should stop every developer in their tracks: Apple spent five years and likely billions of dollars building Memory Integrity Enforcement (MIE) for the M5 chip. A small team at Calif, working with an AI model called Mythos Preview, built a working kernel exploit against it in five days . This isn't a story about Apple failing. It's a story about the state of modern security — and it has real lessons for every developer writing software today. What Exactly Is Memory Integrity Enforcement? Before we get to the exploit, you need to understand what was bypassed. Memory corruption bugs — things like buffer overflows, use-after-free errors, and heap sprays — have been the backbone of software exploits for decades. The reason they keep working is simple: most languages let you do unsafe things with memory, and hardware traditionally didn't care.…
