⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level privileges, allowing attackers to install persistent malware, steal sensitive data, or create backdoors.
Likely Case
Malicious apps from untrusted sources could gain full system control, potentially leading to data theft, surveillance, or ransomware deployment.
If Mitigated
With proper app vetting and security controls, exploitation risk is limited to sophisticated targeted attacks.
🎯 Exploit Status
Exploitation requires a malicious application to be installed and executed on the target device.
