Worst Case
A malicious app could escape sandbox restrictions, gain system-level privileges, install persistent malware, access sensitive user data, and compromise the entire system.
Likely Case
Malicious applications could bypass security restrictions, access files outside their sandbox, and potentially escalate privileges to perform unauthorized actions.
If Mitigated
With proper patch management and application vetting, the risk is limited to unapproved applications attempting sandbox escape, which would be detected by security controls.
🎯 Exploit Status
Exploitation requires user interaction to install/run a malicious application. Public disclosure suggests exploit details are available.
