CVE-2019-0136

What it actually does

Insufficient access control in the Intel PROSet/Wireless WiFi driver permits an adjacent unauthenticated attacker to trigger a denial-of-service condition that affects availability on the impacted host.

Why it matters to the business

Wireless connectivity on affected laptops and desktops can be disrupted by an attacker on the same local network, causing user downtime and potential loss of productivity until the driver is updated or the system is rebooted.

How an attack unfolds

An attacker within adjacent wireless range crafts and sends malformed management or control frames that bypass the driver's access-control checks, causing the WiFi stack to crash or enter an unresponsive state.

How to fix it

Upgrade Intel PROSet/Wireless WiFi Software to version 21.10 or later on all affected platforms; apply vendor-supplied driver updates through Windows Update or Intel Driver & Support Assistant; disable the affected WiFi adapter if an immediate update is not possible.

How to confirm the fix worked

Query the installed driver version via Device Manager or pnputil; confirm the version string is 21.10 or newer; re-test wireless functionality after the update and verify that no crash occurs when subjected to malformed frames in a lab environment.

Typical attack path

1. Gain adjacent network proximity to the target (same Wi-Fi segment or physical range)
2. Send crafted 802.11 frames that exploit the missing access-control validation
3. Trigger repeated driver crashes or resource exhaustion to sustain denial of service

How to detect it

Review system and driver logs for repeated WiFi adapter resets or kernel stack dumps containing references to the Intel wireless driver; correlate with wireless network logs showing unusual volumes of management frames from unknown adjacent stations.

What your security team should do

• Prioritize patching all systems listed in affected products to driver version 21.10 or newer within the next maintenance window
• Inventory endpoints for the vulnerable Intel WiFi driver using endpoint management tools
• Monitor adjacent-network wireless traffic for anomalous management frames as a temporary compensating control
