Worst Case
A malicious application could gain root or system-level privileges, potentially allowing complete compromise of the device, data theft, installation of persistent malware, or bypassing security controls.
Likely Case
A malicious app from the App Store or sideloaded could gain elevated privileges to access protected data, modify system files, or perform unauthorized actions beyond its normal permissions.
If Mitigated
With proper app vetting, sandboxing, and user awareness, the risk is limited to malicious apps that manage to bypass Apple's security checks, though successful exploitation would still be damaging.
🎯 Exploit Status
Exploitation requires a malicious application to be installed and executed on the target device. No public proof-of-concept has been disclosed as of the advisory.
