⚠️ Risk & Real-World Impact
Worst Case
Local attackers could escalate privileges to SYSTEM/root level, potentially gaining full control over endpoints and accessing sensitive data or deploying malware.
Likely Case
Malicious insiders or compromised user accounts could exploit this to bypass security controls, modify enforcement policies, or disable security features.
If Mitigated
With proper access controls and least privilege principles, impact is limited to authorized users who already have some level of system access.
🎯 Exploit Status
Exploitation requires local access but is likely straightforward once access is obtained. No public exploit code is available as of advisory publication.
