# Windows Remote Desktop Client: race condition lets attacker run code remotely

Link for people: https://infrastack.ai/live/CVE-2026-95964 (this .md is for agents)

Race condition (CWE-362) in the Windows Remote Desktop Client lets an unauthorized attacker execute code over a network. Microsoft's CVSS 7.5 (AV:N/AC:H/PR:N/UI:R): high attack complexity and user interaction required. No exploitation or public PoC found. Details come from the CVE record Microsoft published via NVD; the MSRC page could not be read (JavaScript-only).

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

## Affected

- microsoft:Windows 11 24H2 affected < 10.0.26100.9974 fixed 10.0.26100.9974
- microsoft:Windows Server 2025 affected < 10.0.26100.33822 fixed 10.0.26100.33822
- microsoft:Windows Server 2022 affected < 10.0.20348.5870 fixed 10.0.20348.5870
- microsoft:Windows 10 22H2 affected < 10.0.19045.7846 fixed 10.0.19045.7846

## How to check

Check the Windows build (winver, or [System.Environment]::OSVersion) against the fixed builds: Win10 1607/Server 2016 < 10.0.14393.9688; 1809/Server 2019 < 10.0.17763.9487; Win10 21H2/22H2 < 10.0.19044.7846 / 10.0.19045.7846; Server 2022 < 10.0.20348.5870; Win11 23H2 < 10.0.22631.7711; Win11 24H2/25H2 < 10.0.26100.9974 / 10.0.26200.9974; 26H1 < 10.0.28000.3501; 26H2 < 10.0.26300.9974; Server 2025 < 10.0.26100.33822. Prioritise machines that connect to RDP servers they do not control.

## Fix

Install the November 2026 Windows cumulative update that raises the build to at least the fixed number for your version (listed in how-to-check). KB numbers not confirmed; take them from the MSRC page.
