First public macOS kernel exploit on M5 is highly technical and novel but not directly actionable for a senior engineer focused on AI/cloud.
Summary
Researchers from Calif and Mythos Preview demonstrated the first public macOS kernel memory corruption exploit on Apple M5 with MIE (ARM MTE-based hardware memory safety) enabled, bypassing Apple's five-year, billion-dollar mitigation in five days. The data-only local privilege escalation chain targets macOS 26.4.1, using two vulnerabilities and AI-assisted tooling to generalize known bug classes. Full technical details will be published after Apple ships a fix.
