INTEL PROSET/WIRELESS WI-FI SOFTWARE · CVE-2026-40433 · Infrastructure
FIX → 24.50 ✓ verified
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.

Free first check from your website. Connect your repo for the full answer.
Windows laptops and desktops with an Intel Wi-Fi adapter (discrete or integrated in 10th-14th gen Core and Core Ultra) running PROSet/Wireless Wi-Fi software before 24.50. An attacker on the same (adjacent) network can trigger a kernel heap overflow without credentials or user action, causing denial of service; Intel rates integrity and availability impact high. Linux, macOS and machines without Intel Wi-Fi can skip it.
Not affected if default-windows-driver, driver-24.50-or-later, linux, macos, no-intel-wifi-hardware, non-intel-wifi
Who cares adjacent-network, intel-wifi, kernel, laptops, windows
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.
