⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level code execution, allowing attackers to gain SYSTEM privileges, install persistent malware, or disable security controls.
Likely Case
Local privilege escalation from a standard user account to SYSTEM/administrator privileges, enabling further lateral movement or persistence establishment.
If Mitigated
Limited impact if proper endpoint protection and least privilege principles are enforced, though kernel-level vulnerabilities remain serious.
🎯 Exploit Status
Requires local access and ability to interact with the vulnerable driver. Kernel exploitation adds complexity but driver vulnerabilities are often targeted.
🛠️ Fix & Mitigation
