CVE-2023-32282
📋 TL;DR
A race condition vulnerability in BIOS firmware for certain Intel processors allows a privileged user with local access to potentially escalate privileges. This affects systems using vulnerable Intel processors and requires BIOS-level exploitation. The vulnerability enables attackers to bypass security controls and gain higher system privileges.
💻 Affected Systems
- Intel processors with vulnerable BIOS firmware
⚠️ 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.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level access, allowing installation of persistent malware, data theft, and lateral movement across the network.
Likely Case
Privilege escalation from a lower-privileged account to SYSTEM/root level access on the affected machine.
If Mitigated
Limited impact if proper BIOS updates are applied and privilege separation is enforced.
🎯 Exploit Status
Exploitation requires local access, privileged initial foothold, and precise timing due to race condition nature.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: BIOS/UEFI firmware updates from system manufacturers
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00929.html
Restart Required: Yes
Instructions:
1. Check system manufacturer's website for BIOS/UEFI updates. 2. Download appropriate firmware update. 3. Follow manufacturer's instructions to flash BIOS. 4. Reboot system. 5. Verify BIOS version is updated.
🔧 Temporary Workarounds
Restrict local access
allLimit physical and remote local access to vulnerable systems
Principle of least privilege
allEnforce strict privilege separation to limit initial foothold
🧯 If You Can't Patch
- Isolate vulnerable systems in separate network segments
- Implement strict access controls and monitoring for privileged accounts
🔍 How to Verify
Check if Vulnerable:
Check BIOS/UEFI version against manufacturer's patched versions. Use systeminfo on Windows or dmidecode on Linux.Check Version:
Windows: wmic bios get smbiosbiosversion | Linux: sudo dmidecode -s bios-versionVerify Fix Applied:
Verify BIOS version matches patched version from manufacturer after update.📡 Detection & Monitoring
Log Indicators:
- Unusual BIOS/UEFI access attempts
