⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with SYSTEM privileges, enabling installation of persistent malware, credential theft, lateral movement, and data exfiltration from medical systems.
Likely Case
Local attacker gains SYSTEM privileges on the compromised workstation, potentially accessing sensitive medical data and using the system as a pivot point within the network.
If Mitigated
With proper access controls and monitoring, impact limited to single workstation compromise with rapid detection and containment.
🎯 Exploit Status
Requires local access and timing precision for race condition exploitation. No public exploit code identified in references.
