⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the Hyper-V host, allowing attacker to control all guest VMs, access host data, and pivot to other systems.
Likely Case
Privilege escalation from guest VM to host, enabling lateral movement and data exfiltration.
If Mitigated
Limited impact due to network segmentation, strict access controls, and monitoring preventing successful exploitation.
🎯 Exploit Status
Requires authenticated access to a guest VM and specific conditions to trigger the vulnerability.
