⚠️ Risk & Real-World Impact
Worst Case
A privileged attacker could extract sensitive information from UEFI firmware, potentially including system configuration data or credentials stored in firmware.
Likely Case
A malicious administrator or compromised privileged account could access limited system information from firmware that should be protected.
If Mitigated
With proper access controls and monitoring, impact is limited to information disclosure only, not system compromise.
🎯 Exploit Status
Requires local privileged access. No public exploit code known at this time.
🛠️ Fix & Mitigation
