macOS Kernel Memory Corruption Exploit

Multiple high-impact security stories: a team used Anthropic’s Mythos (and other LLMs like GPT‑5.5) to locate and quickly develop a working macOS kernel memory-corruption exploit for Apple M‑series hardware; a public zero‑day exploit named YellowKey reliably bypasses default Windows 11 BitLocker protections (requires physical access and TPM access); the widespread Linux local privilege‑escalation “copy.fail” vulnerability (CVE-2026-31431) with a public PoC allows arbitrary writes into page cache and affects many distributions; researchers also demonstrated simple bypasses of AI-based on‑camera
