⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM privileges, enabling installation of persistent malware, data theft, and lateral movement across the network.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, install additional payloads, and maintain persistence on compromised systems.
If Mitigated
Limited impact if proper endpoint protection, driver signature enforcement, and least privilege principles are implemented.
🎯 Exploit Status
Exploit code is publicly available on GitHub, making exploitation straightforward for attackers with local access.
