# CVE-2026-40433: CVE-2026-40433

Status: published. Published: 2026-11-10. Updated: 2026-11-12.

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.
