⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with persistent SMM rootkit installation, allowing attackers to bypass all security controls including operating system protections, hypervisors, and security software.
Likely Case
Privilege escalation to SMM level, enabling attackers to execute arbitrary code with highest system privileges, potentially leading to data theft, ransomware deployment, or system persistence.
If Mitigated
Limited impact if SMM protections are properly configured and firmware integrity is verified, though risk remains due to the privileged nature of SMM.
🎯 Exploit Status
Exploitation likely requires physical access or administrative privileges; SMM exploitation is complex but highly impactful
