AI BriefingFirst Publicly Disclosed macOS Kernel Memory Corruption Vulnerability on Apple M5
Key point
Using the AI tool Mythos Preview, engineers developed a macOS kernel exploit that bypasses Apple M5's MIE security feature.
Details
Calif engineers developed a macOS kernel memory corruption exploit running on Apple M5 silicon and delivered it directly to Apple.
This exploit chain targets bare-metal M5 hardware with MIE (Memory Integrity Enforcement) enabled, achieving a data-only kernel privilege escalation that allows an unprivileged local user to reach a root shell using only ordinary system calls.
Key points are as follows:
- AI-driven development: An AI tool called Mythos Preview supported the entire process of bug identification and exploit development. The AI contributed by quickly finding issue types it had already learned.
- Bypassing security mitigations: Fully autonomous bypass of cutting-edge hardware security technologies like MIE still required human expert involvement, but the combination of AI and experts completed the kernel exploit in just 1 week.
- AI as a security threat: This case is an important indicator of the real-world pressure that AI-driven bug discovery techniques are placing on top-tier security defense systems.
