Worst Case
A malicious app could gain root or system-level privileges, potentially compromising the entire device, accessing sensitive data, or installing persistent malware.
Likely Case
Malicious apps from untrusted sources could bypass sandbox restrictions, access user data, or perform unauthorized actions with elevated permissions.
If Mitigated
With proper app vetting and security controls, the risk is limited to sophisticated targeted attacks rather than widespread exploitation.
🎯 Exploit Status
Exploitation requires a malicious application to be installed and executed on the target device. No public exploit code is currently available.
