# Windows DWM Core Library: type confusion lets a local user gain SYSTEM-level privileges

Link for people: https://infrastack.ai/live/CVE-2026-105575 (this .md is for agents)

A type confusion flaw in the Windows Desktop Window Manager Core Library lets an authorized local attacker elevate their privileges. The sources do not describe further conditions.

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

## Affected

- vendor:Windows DWM Core Library affected range not listed fixed no fixed version listed
- vendor:Windows 11 24H2 affected >= 10.0.26100.0, < 10.0.26100.9974 fixed 10.0.26100.9974
- vendor:Windows 11 23H2 affected >= 10.0.22631.0, < 10.0.22631.7711 fixed 10.0.22631.7711
- vendor:Windows 10 22H2 affected >= 10.0.19045.0, < 10.0.19045.7846 fixed 10.0.19045.7846
- vendor:Windows Server 2022 affected >= 10.0.20348.0, < 10.0.20348.5870 fixed 10.0.20348.5870
- vendor:Windows Server 2025 affected >= 10.0.26100.0, < 10.0.26100.33822 fixed 10.0.26100.33822
- vendor:Windows Server 2019 affected >= 10.0.17763.0, < 10.0.17763.9487 fixed 10.0.17763.9487

## How to check

Run winver (or [System.Environment]::OSVersion.Version / cmd 'ver') and compare the full build number with the fixed build for your Windows version; anything lower is affected.

## Fix

Install the November 2026 Windows cumulative update: Win10 1809/Server 2019 10.0.17763.9487; Win10 21H2 10.0.19044.7846; Win10 22H2 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974; Win11 25H2 10.0.26200.9974; Win11 26H2 10.0.26300.9974; Server 2022 10.0.20348.5870; Server 2025 10.0.26100.33822
