⚠️ Risk & Real-World Impact
Worst Case
An attacker gains full system-level privileges on the device, potentially accessing sensitive data, installing malware, or bypassing security controls.
Likely Case
Malicious apps escalate privileges to access protected resources, modify system settings, or perform unauthorized actions without user consent.
If Mitigated
With proper app vetting and security controls, exploitation attempts are detected and blocked before privilege escalation occurs.
🎯 Exploit Status
Requires malicious app installation but no user interaction for exploitation once installed. Local access to device needed.
