CVE-2023-38417

What it actually does

Improper input validation in Intel PROSet/Wireless WiFi software allows an unauthenticated adjacent attacker to trigger denial of service.

Why it matters to the business

Wireless connectivity disruptions that can interrupt operations for devices relying on the affected software, with low exploitation likelihood given stable low EPSS and no KEV listing.

How an attack unfolds

An attacker with adjacent network access crafts malformed inputs targeting the wireless software, exploiting the validation flaw to cause service failure without authentication.

How to fix it

Upgrade Intel PROSet/Wireless WiFi software to version 23.20 or later to address the input validation issue.

How to confirm the fix worked

Confirm the installed Intel PROSet/Wireless WiFi software version is 23.20 or higher and test for continued service availability under adjacent network conditions.

Typical attack path

1. Obtain adjacent network access
2. Transmit specially crafted wireless frames or inputs to the vulnerable software
3. Trigger service crash or resource exhaustion resulting in denial of service

How to detect it

Review system and wireless driver logs for unexpected crashes or restarts coinciding with adjacent network activity; no known threat actor campaigns apply to this issue.

What your security team should do

• Prioritize upgrade of all instances of the affected Intel wireless software to the fixed version
• Limit unnecessary adjacent network exposure for wireless-enabled systems
• Monitor network logs for wireless service instability
