CVE-2024-22376
📋 TL;DR
This vulnerability in Intel Ethernet Adapter Driver Pack allows authenticated local users to escalate privileges by manipulating the software's search path. It affects systems with Intel Ethernet adapters using driver versions before 28.3. Attackers could gain elevated system access if they can place malicious files in specific directories.

⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains SYSTEM/root privileges, enabling complete system compromise, data theft, persistence installation, and lateral movement.
Likely Case
Local authenticated users (including low-privilege accounts) escalate to administrative privileges, allowing them to install malware, modify system settings, or access protected data.
If Mitigated
With proper access controls and monitoring, exploitation attempts are detected and blocked, limiting impact to isolated systems.
🎯 Exploit Status
Exploitation requires local authenticated access and ability to place files in specific directories. No public exploit code is known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 28.3 or later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01106.html
Restart Required: Yes
Instructions:
1. Download Intel Ethernet Adapter Driver Pack version 28.3 or later from Intel's website. 2. Run the installer with administrative privileges. 3. Follow on-screen instructions. 4. Restart the system when prompted.
🔧 Temporary Workarounds
Restrict directory permissions
allLimit write access to directories in the search path to prevent malicious file placement
Windows: icacls "C:\Program Files\Intel\Ethernet\" /deny Users:(OI)(CI)W
Linux: chmod 755 /usr/lib/intel/ethernet/ && chown root:root /usr/lib/intel/ethernet/*
Remove vulnerable driver
allUninstall the vulnerable driver pack if not required
Windows: Control Panel > Programs > Uninstall Intel Ethernet Adapter Driver Pack
Linux: sudo apt remove intel-ethernet-driver-pack (Debian/Ubuntu) or sudo yum remove intel-ethernet-driver-pack (RHEL/CentOS)
🧯 If You Can't Patch
- Implement strict access controls to limit who can log into affected systems
- Monitor for privilege escalation attempts and file creation in driver directories
🔍 How to Verify
Check if Vulnerable:
Check driver version in device manager (Windows) or run 'ethtool -i <interface>' (Linux) and compare version to 28.3Check Version:
Windows: Get-WmiObject Win32_PnPSignedDriver | Where-Object {$_.DeviceName -like '*Intel*Ethernet*'} | Select-Object DeviceName, DriverVersion
Linux: ethtool -i <interface_name> | grep versionVerify Fix Applied:
Verify driver version is 28.3 or later and check that directory permissions are properly restricted📡 Detection & Monitoring
Log Indicators:
- Unexpected file creation in Intel driver directories
- Privilege escalation events in security logs
- Driver installation/modification by non-admin users
Network Indicators:
- Unusual outbound connections from systems with Intel Ethernet adapters
