⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM privileges, enabling installation of persistent malware, credential theft, and lateral movement across the network.
Likely Case
Local privilege escalation from standard user to administrator/SYSTEM level, allowing attackers to bypass security controls and install additional payloads.
If Mitigated
Limited impact with proper endpoint protection, least privilege enforcement, and network segmentation preventing lateral movement.
🎯 Exploit Status
Requires authenticated access and local execution. Use-after-free vulnerabilities typically require precise timing and memory manipulation.
