CVE-2026-57092

Windows VMSwitch is part of Windows that helps network connectivity work correctly for virtualized networking. In this vulnerability, a mistake in how memory is handled can be abused by someone who already has some authorization to get much higher control over the device—potentially turning into a full system compromise.

This matters if you run supported Windows desktops or servers (Windows 10, Windows 11, and the listed Windows Server versions). The risk is primarily for systems an attacker can reach over the network, and it requires the attacker to be authorized and connected; there’s no need for you to click anything.

This is RED because it allows privilege escalation remotely in Windows VMSwitch, meaning an attacker who has some level of authorization can gain significantly higher control without user interaction. While no clear public dated exploitation report or public exploit code is shown in the findings, the impact is critical and Microsoft has released fixes for many OS branches.
