CVE-2024-31068

5.3 MEDIUM

📋 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

Products:
  • Intel processors with specific hardware logic implementations
Versions: Specific processor models not publicly detailed in advisory
Operating Systems: All operating systems running on affected Intel processors
Default Config Vulnerable: ⚠️ Yes
Notes: Requires local privileged access; exact processor models not fully disclosed in public advisory

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ 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

🌐 Internet-Facing: LOW - requires local privileged access, not remotely exploitable
🏢 Internal Only: MEDIUM - insider threat or compromised privileged account could cause service disruption

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: HIGH - requires deep hardware knowledge and privileged access

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

all

Limit local administrative/root access to trusted personnel only

Monitor system stability

all

Implement 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

📡 Detection & Monitoring

Log Indicators:

  • Unexpected system crashes
  • Kernel panic logs
  • Hardware error logs

Network Indicators:

  • None - local attack only

SIEM Query:

EventID=41 OR 'kernel panic' OR 'hardware error' OR 'system crash'
