CVE-2025-24325

8.8 HIGH

📋 TL;DR

An improper input validation vulnerability in Intel 800 Series Ethernet kernel-mode drivers allows authenticated local users to potentially escalate privileges. This affects Linux systems using vulnerable Intel Ethernet drivers. Attackers with local access could gain root privileges on affected systems.

💻 Affected Systems

Products:
  • Intel 800 Series Ethernet Controllers
  • Linux kernel-mode driver for Intel 800 Series Ethernet
Versions: All versions before 1.17.2
Operating Systems: Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with Intel 800 Series Ethernet hardware and vulnerable driver versions installed.

⚠️ 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).

🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.

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

Local authenticated attacker gains root privileges, leading to complete system compromise, data theft, and persistence establishment.

🟠

Likely Case

Privileged user or attacker with initial access escalates to root to install malware, steal credentials, or pivot to other systems.

🟢

If Mitigated

With proper access controls and monitoring, exploitation attempts are detected and contained before significant damage occurs.

🌐 Internet-Facing: LOW - Requires local authenticated access, not directly exploitable over network.
🏢 Internal Only: HIGH - Local authenticated access is common in enterprise environments, making internal systems prime targets.

🎯 Exploit Status

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

Requires local authenticated access and knowledge of driver internals. No public exploit code available at advisory publication.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.17.2 or later

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01296.html

Restart Required: Yes

Instructions:

1. Check current driver version. 2. Download updated driver from Intel. 3. Install new driver following Intel instructions. 4. Reboot system to load patched driver.

🔧 Temporary Workarounds

Restrict local user access

linux

Limit local user accounts and implement least privilege to reduce attack surface

Disable affected hardware

linux

Temporarily disable Intel 800 Series Ethernet if not critical

sudo modprobe -r ixgbe
sudo modprobe -r i40e

🧯 If You Can't Patch

  • Implement strict access controls to limit local user privileges
  • Deploy endpoint detection and response (EDR) to monitor for privilege escalation attempts

🔍 How to Verify

Check if Vulnerable:

Check installed driver version: modinfo ixgbe | grep version OR modinfo i40e | grep version

Check Version:

modinfo ixgbe | grep version; modinfo i40e | grep version

Verify Fix Applied:

Verify driver version is 1.17.2 or higher: modinfo ixgbe | grep version OR modinfo i40e | grep version

📡 Detection & Monitoring

Log Indicators:

  • Kernel logs showing driver crashes or unexpected privilege changes
  • Audit logs showing unusual process privilege escalation

Network Indicators:

  • Unusual outbound connections from privileged processes

SIEM Query:

source="kernel" AND ("ixgbe" OR "i40e") AND ("segfault" OR "panic" OR "oops")
