First public macOS kernel memory corruption exploit on Apple M5 | Hacker News

A Hacker News thread discussed a possible first public exploit for a macOS kernel memory corruption issue on Apple M5 Macs.

Commenters debated the exploit path and whether Apple’s Memory Tagging Extension and bounds checking should have blocked it.

The discussion suggested the attack may involve bypassing multiple memory protections, including kernel and GPU-related defenses.

If confirmed, the finding would point to a real-world weakness in Apple’s latest security stack on M5 devices.
