CVE-2024-39356

7.4 HIGH

📋 TL;DR

A NULL pointer dereference vulnerability in Intel PROSet/Wireless WiFi and Killer WiFi software for Windows allows unauthenticated attackers on the same network to potentially cause denial of service by crashing the WiFi software. This affects Windows systems running vulnerable versions of these Intel WiFi drivers and management software.

💻 Affected Systems

Products:
  • Intel PROSet/Wireless WiFi software
  • Intel Killer WiFi software
Versions: All versions before 23.80
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with vulnerable Intel WiFi adapters and software installed. Requires attacker to be on the same network segment.

⚠️ 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).

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

Complete disruption of WiFi connectivity on affected systems, requiring system reboot to restore functionality.

🟠

Likely Case

Temporary WiFi service disruption affecting individual workstations, potentially requiring user intervention to restart WiFi services.

🟢

If Mitigated

Limited impact with proper network segmentation and updated software, potentially affecting only isolated systems.

🌐 Internet-Facing: LOW - Requires adjacent network access, not directly exploitable from the internet.
🏢 Internal Only: MEDIUM - Attackers on the same local network could disrupt WiFi connectivity for affected systems.

🎯 Exploit Status

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

Exploitation requires network adjacency and specific conditions to trigger the NULL pointer dereference.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version 23.80 or later

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01224.html

Restart Required: No

Instructions:

1. Download Intel Driver & Support Assistant or visit Intel Download Center. 2. Check for WiFi driver updates. 3. Install version 23.80 or newer. 4. Verify installation through device manager.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate vulnerable systems from untrusted networks to prevent adjacent access exploitation.

Disable Vulnerable WiFi Adapters

windows

Temporarily disable Intel WiFi adapters if patching is not immediately possible.

netsh interface set interface "Wi-Fi" admin=disable

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate vulnerable systems
  • Monitor for WiFi service disruptions and investigate potential exploitation attempts

🔍 How to Verify

Check if Vulnerable:

Check Intel PROSet/Wireless WiFi software version in Control Panel > Programs and Features or via Device Manager > Network adapters > Intel WiFi adapter > Driver tab.

Check Version:

wmic product where "name like '%Intel%WiFi%'" get name,version

Verify Fix Applied:

Confirm software version is 23.80 or higher in Programs and Features or Device Manager driver details.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected WiFi service crashes
  • Event logs showing WiFi adapter failures
  • System logs indicating NULL pointer exceptions in WiFi drivers

Network Indicators:

  • Unusual network traffic patterns targeting WiFi management ports
  • Multiple WiFi disconnection events from same source

SIEM Query:

source="windows" AND (event_id=1000 OR event_id=1001) AND process_name="*wlan*" OR description="*NULL*"
