CVE-2022-37410

7.0 HIGH

📋 TL;DR

This vulnerability in Intel Thunderbolt driver software allows authenticated local users to escalate privileges due to improper access control. It affects systems with vulnerable Thunderbolt drivers before version 89. Attackers with local access could gain higher system privileges.

💻 Affected Systems

Products:
  • Intel Thunderbolt driver software
Versions: All versions before 89
Operating Systems: Windows, Linux systems with Thunderbolt support
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Thunderbolt hardware and vulnerable driver installation. Systems without Thunderbolt ports are not affected.

⚠️ 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).

  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

An authenticated attacker could gain SYSTEM/root privileges, install malware, access sensitive data, or compromise the entire system.

🟠

Likely Case

Local users could elevate privileges to install unauthorized software, modify system settings, or access restricted resources.

🟢

If Mitigated

With proper access controls and patching, impact is limited to authorized users only performing legitimate actions.

🌐 Internet-Facing: LOW - Requires local access, not remotely exploitable over network.
🏢 Internal Only: HIGH - Local authenticated access is common in enterprise environments, making this a significant internal threat.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Requires authenticated local access. No public exploit code available at time of analysis.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version 89 or later

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00916.html

Restart Required: Yes

Instructions:

1. Visit Intel Driver & Support Assistant or download center
2. Download Thunderbolt driver version 89 or newer
3. Install the updated driver
4. Restart the system

🔧 Temporary Workarounds

Disable Thunderbolt ports

all

Disable Thunderbolt functionality in BIOS/UEFI settings to prevent driver exploitation

Restrict local access

all

Implement strict local access controls and limit user privileges

🧯 If You Can't Patch

  • Disable Thunderbolt ports in BIOS/UEFI settings
  • Implement strict local access controls and principle of least privilege
  • Monitor for privilege escalation attempts and unusual driver activity

🔍 How to Verify

Check if Vulnerable:

Check Thunderbolt driver version in Device Manager (Windows) or via 'lspci -v' and driver info (Linux). Version below 89 indicates vulnerability.

Check Version:

Windows: Check in Device Manager under 'System devices' > 'Thunderbolt Controller'. Linux: Check via 'modinfo thunderbolt' or driver version in dmesg.

Verify Fix Applied:

Confirm Thunderbolt driver version is 89 or higher after update.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected privilege escalation events
  • Thunderbolt driver loading/unloading anomalies
  • Security event logs showing local privilege changes

Network Indicators:

  • Not applicable - local exploit only

SIEM Query:

Windows Security Event ID 4672 (Special privileges assigned) OR Sysmon Event ID 10 (Process access) targeting high-privilege processes from Thunderbolt-related executables
