# Intel Wi-Fi driver for Windows: heap overflow in kernel crashes the system

Link for people: https://infrastack.ai/live/CVE-2026-40433 (this .md is for agents)

Some Intel PROSet Wireless Wi-Fi software for Windows has a heap-based buffer overflow in its kernel-level (Ring 0) code. A nearby network attacker can trigger it without credentials or user action, causing denial of service and potentially high integrity and availability impact.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Intel PROSet/Wireless Wi-Fi software affected < 24.50 fixed 24.50

## How to check

Find the installed Intel PROSet/Wireless Wi-Fi software or driver version (Device Manager > Network adapters > Intel Wi-Fi adapter > Driver tab, or Installed apps). Versions before 24.50 are affected. Affected adapters: Wireless-AC 9260/9461/9462/9560, Wi-Fi 6 AX201, Wi-Fi 6E AX210/AX211, Wi-Fi 7 BE200/BE201 (and Killer equivalents), plus integrated Wi-Fi on Intel Core 10th-14th gen and Core Ultra Series 1/2. Also check laptop-maker (e.g. Dell) driver updates, which may lag Intel's.

## Fix

Update Intel PROSet/Wireless Wi-Fi software to version 24.50 or later (exe installer or IT admin package from Intel download center).

## From the sources

Heap-based buffer overflow for some Intel(R) PROSet Wireless Wi-Fi Software for Windows within Ring 0: Kernel may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (high) impacts.
