CVE-2025-22830
📋 TL;DR
This CVE describes a race condition vulnerability in AMI APTIOV BIOS that allows a skilled local attacker to cause resource exhaustion. Exploitation could compromise confidentiality, integrity, and availability of affected systems. This affects systems using vulnerable AMI BIOS firmware.
💻 Affected Systems
- AMI APTIOV BIOS
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including BIOS-level persistence, data theft, and denial of service through resource exhaustion.
Likely Case
System instability, crashes, or temporary denial of service requiring physical reset.
If Mitigated
Limited impact with proper BIOS write protection and physical security controls in place.
🎯 Exploit Status
Requires skilled attacker with local access; race condition exploitation requires precise timing
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to AMI security advisory for specific patched versions
Vendor Advisory: https://go.ami.com/hubfs/Security%20Advisories/2025/AMI-SA-2025006.pdf
Restart Required: Yes
Instructions:
1. Download BIOS update from system manufacturer. 2. Follow OEM-specific BIOS update procedures. 3. Apply update and restart system. 4. Verify BIOS version after update.
🔧 Temporary Workarounds
Physical Security Controls
allRestrict physical access to vulnerable systems to prevent local exploitation
BIOS Write Protection
allEnable BIOS write protection if supported by hardware to prevent unauthorized modifications
🧯 If You Can't Patch
- Implement strict physical access controls to prevent unauthorized local access
- Monitor systems for unusual BIOS-related activity or system instability
🔍 How to Verify
Check if Vulnerable:
Check BIOS version against vendor advisory; use system BIOS/UEFI setup utility or manufacturer diagnostic toolsCheck Version:
System-specific commands vary by manufacturer; typically accessed via BIOS setup or manufacturer utilitiesVerify Fix Applied:
Verify BIOS version matches patched version from vendor advisory after update📡 Detection & Monitoring
Log Indicators:
- Unexpected system reboots
- BIOS/UEFI firmware modification attempts
- System instability logs
Network Indicators:
- None - local exploitation only
SIEM Query:
Search for: (EventID related to system crashes OR BIOS/UEFI events) AND (source system with vulnerable BIOS)
