7.9 HIGH

📋 TL;DR

A NULL pointer dereference vulnerability in Intel MLC software before version 3.11b allows authenticated local users to potentially cause denial of service. This affects systems running vulnerable versions of Intel MLC software, primarily impacting environments where this memory latency checker tool is deployed.

💻 Affected Systems

Products:
  • Intel Memory Latency Checker (MLC) software
Versions: All versions before v3.11b
Operating Systems: Linux, Windows, Other supported OS for Intel MLC
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Intel MLC software to be installed and accessible to authenticated local users.

⚠️ 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.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system crash or kernel panic requiring physical reboot, disrupting all services on the affected system.

🟠

Likely Case

Application crash or system instability affecting the MLC software functionality and potentially related processes.

🟢

If Mitigated

Minimal impact with proper access controls limiting local authenticated user privileges.

🌐 Internet-Facing: LOW - Requires local authenticated access, not remotely exploitable.
🏢 Internal Only: MEDIUM - Authenticated local users could disrupt system availability in environments with vulnerable MLC installations.

🎯 Exploit Status

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

Requires authenticated local access and specific conditions to trigger the NULL pointer dereference.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v3.11b or later

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01238.html

Restart Required: No

Instructions:

1. Download Intel MLC v3.11b or later from Intel's website. 2. Stop any running MLC processes. 3. Install the updated version following Intel's installation guide. 4. Verify the new version is running correctly.

🔧 Temporary Workarounds

Restrict MLC access

all

Limit access to Intel MLC software to only trusted administrators

chmod 750 /path/to/mlc
chown root:root /path/to/mlc

Remove MLC if unused

Linux

Uninstall Intel MLC software if not required for operations

sudo apt remove intel-mlc
sudo yum remove intel-mlc

🧯 If You Can't Patch

  • Implement strict access controls to prevent unauthorized users from executing MLC
  • Monitor system logs for MLC-related crashes or unusual activity

🔍 How to Verify

Check if Vulnerable:

Check Intel MLC version: ./mlc --version or check installed package version

Check Version:

./mlc --version 2>&1 | grep -i version

Verify Fix Applied:

Confirm version is v3.11b or later and test basic MLC functionality
