⚠️ Risk & Real-World Impact
Worst Case
Privileged attacker could access sensitive system information, firmware data, or security configurations that should be protected.
Likely Case
Information disclosure of system security settings or firmware data to a local privileged user.
If Mitigated
Minimal impact with proper access controls and monitoring of privileged user activities.
🎯 Exploit Status
Requires local privileged access and race condition timing to exploit successfully.
