⚠️ Risk & Real-World Impact
Worst Case
Full device compromise including kernel-level persistence, data exfiltration, and complete bypass of security controls.
Likely Case
Privilege escalation leading to installation of persistent malware, surveillance capabilities, or data theft.
If Mitigated
Limited impact due to exploit complexity requiring initial kernel access and patched systems being immune.
🎯 Exploit Status
Apple confirms exploitation in the wild. Requires kernel read/write capability as prerequisite.
