CVE-2025-24486
📋 TL;DR
This vulnerability allows an authenticated local user to potentially escalate privileges through improper input validation in Intel 700 Series Ethernet kernel-mode drivers. It affects Linux systems using these specific Intel Ethernet adapters. The attacker must already have local access to the system.
💻 Affected Systems
- Intel(R) 700 Series Ethernet Controllers
⚠️ 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
An authenticated attacker gains full root/system privileges, allowing complete system compromise, data theft, persistence establishment, and lateral movement.
Likely Case
Privilege escalation from a standard user account to root, enabling installation of malware, configuration changes, and access to sensitive data.
If Mitigated
Limited impact due to proper access controls, minimal user privileges, and network segmentation restricting lateral movement.
🎯 Exploit Status
Requires local authenticated access and knowledge of driver interaction. No public exploit code known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.28.5
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01335.html
Restart Required: Yes
Instructions:
1. Download Intel Ethernet driver version 2.28.5 or newer from Intel's website. 2. Stop network services. 3. Unload current driver module. 4. Install updated driver. 5. Reboot system. 6. Verify driver version.
🔧 Temporary Workarounds
Restrict local user access
linuxLimit local user accounts and implement least privilege to reduce attack surface.
Disable vulnerable driver
linuxBlacklist or prevent loading of the vulnerable Intel Ethernet driver if alternative networking is available.
echo 'blacklist igb' >> /etc/modprobe.d/blacklist.conf
update-initramfs -u
🧯 If You Can't Patch
- Implement strict access controls and limit local user accounts to trusted personnel only.
- Monitor for privilege escalation attempts and unusual driver activity using system logs and security tools.
🔍 How to Verify
Check if Vulnerable:
Check loaded driver version with: modinfo igb | grep versionCheck Version:
modinfo igb | grep versionVerify Fix Applied:
Verify driver version is 2.28.5 or higher: modinfo igb | grep version📡 Detection & Monitoring
Log Indicators:
- Failed privilege escalation attempts
- Unusual driver module loading/unloading
- Kernel crash dumps related to igb driver
Network Indicators:
- None - local exploitation only
