FIRST PUBLIC MACOS KERNEL MEMORY CORRUPTION EXPLOIT ON APPLE M5

Summary from the TLDR Dev newsletter

Researchers successfully developed the first public macOS kernel memory corruption exploit targeting the new Apple M5 silicon despite its advanced hardware-based security features. This breach bypassed the Memory Integrity Enforcement system, a multi-billion-dollar defense mechanism designed over five years to make such memory-based attacks obsolete. However, Anthropic's Mythos Preview model was used to find and exploit these vulnerabilities in just five days.
