CVE-2024-36326
📋 TL;DR
This vulnerability in AMD RomArmor allows attackers to bypass security protections during system resume from standby, potentially accessing sensitive data or modifying system behavior. It affects systems with AMD processors using RomArmor technology. Attackers need local access to exploit this flaw.
💻 Affected Systems
- AMD processors with RomArmor technology
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attacker gains full system control, extracts encryption keys or sensitive firmware data, and establishes persistent backdoor access.
Likely Case
Attacker with local access bypasses security controls to read protected memory regions or modify system configuration.
If Mitigated
With proper access controls and monitoring, impact limited to unauthorized memory reads without system compromise.
🎯 Exploit Status
Requires local system access and knowledge of RomArmor implementation details
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to AMD advisory for specific BIOS/UEFI firmware updates
Vendor Advisory: https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-4012.html
Restart Required: Yes
Instructions:
1. Check AMD advisory for affected processor models
2. Download updated BIOS/UEFI firmware from system/motherboard manufacturer
3. Follow manufacturer's firmware update instructions
4. Reboot system to apply firmware update
🔧 Temporary Workarounds
Disable standby/sleep states
allPrevent system from entering standby/sleep states where vulnerability is exploitable
powercfg -h off
systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
Enhanced access controls
allImplement strict local access controls and monitoring for privileged operations
🧯 If You Can't Patch
- Implement strict physical security controls to prevent unauthorized local access
- Disable standby/sleep functionality and require full shutdowns between uses
🔍 How to Verify
Check if Vulnerable:
Check AMD advisory for affected processor models and compare with your system's CPU informationCheck Version:
wmic bios get smbiosbiosversion (Windows) or dmidecode -t bios (Linux)Verify Fix Applied:
Verify BIOS/UEFI firmware version matches patched version from manufacturer📡 Detection & Monitoring
Log Indicators:
- Unexpected system resume events
- Unauthorized firmware access attempts
- Suspicious local privilege escalation
Network Indicators:
- Not network exploitable - focus on local system monitoring
SIEM Query:
EventID=1 OR EventID=12 (Windows) with suspicious process creation during resume events
