CVE-2026-20727 · Severity: high · CVSS 8.6 · Published 2026-08-11

Intel PROSet/Wireless WiFi Software is a driver and management suite for wireless network adapters on Windows systems. A null pointer dereference in the kernel-mode component can be triggered by an unauthenticated attacker over the network, causing the system to crash and become unavailable. This vulnerability requires no special privileges or user interaction, making it a straightforward avenue for attackers to cause service disruptions.
