⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM-level privileges, enabling installation of malware, data theft, or persistence mechanisms.
Likely Case
Local privilege escalation from standard user to administrator or SYSTEM privileges, allowing unauthorized access to sensitive resources.
If Mitigated
Limited impact if proper access controls and privilege separation are implemented, though local attackers could still gain elevated access.
🎯 Exploit Status
Exploitation requires local access and race condition timing precision. No public exploit code is currently available.
