CVE-2024-31068
📋 TL;DR
This vulnerability involves improper finite state machine implementation in hardware logic for certain Intel processors, allowing a privileged user to potentially cause denial of service via local access. It affects systems with specific Intel processors and requires local privileged access to exploit.
💻 Affected Systems
- Intel processors with specific hardware logic implementations
⚠️ 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).

⚠️ Risk & Real-World Impact
Worst Case
System crash or hang requiring physical power cycle, potentially affecting multiple systems if exploited in orchestrated attack
Likely Case
Local denial of service affecting single system availability, requiring reboot to restore functionality
If Mitigated
Minimal impact with proper access controls limiting privileged users
🎯 Exploit Status
Exploitation requires privileged local access and understanding of processor hardware logic
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Microcode updates and BIOS/UEFI firmware updates
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01166.html
Restart Required: Yes
Instructions:
1. Check Intel advisory for affected processor models. 2. Contact hardware vendor for BIOS/UEFI firmware updates. 3. Apply microcode updates through operating system updates. 4. Reboot system to apply changes.
🔧 Temporary Workarounds
Restrict privileged access
allLimit local administrative/root access to trusted personnel only
Monitor system stability
allImplement monitoring for unexpected system crashes or hangs
🧯 If You Can't Patch
- Implement strict access controls to limit local privileged users
- Monitor systems for unusual crash patterns and maintain good backups
🔍 How to Verify
Check if Vulnerable:
Check Intel processor model and compare with Intel advisory list; check microcode version
Check Version:
Linux: cat /proc/cpuinfo | grep 'model name'; Windows: wmic cpu get name
Verify Fix Applied:
Verify BIOS/UEFI firmware version matches vendor's patched version; check microcode update applied
