# Windows Desktop Window Manager: out-of-bounds read lets a local user gain SYSTEM-level privileges

Link for people: https://infrastack.ai/live/CVE-2026-113758 (this .md is for agents)

Microsoft's Desktop Window Manager, the Windows component that draws the desktop, has an out-of-bounds read flaw. An attacker who already has a local account can elevate their privileges on the machine.

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

## Affected

- vendor:Windows 10 1607 / Server 2016 affected >= 10.0.14393.0, < 10.0.14393.9688 fixed 10.0.14393.9688
- vendor:Windows 10 1809 / Server 2019 affected >= 10.0.17763.0, < 10.0.17763.9487 fixed 10.0.17763.9487
- vendor:Windows 10 21H2 affected >= 10.0.19044.0, < 10.0.19044.7846 fixed 10.0.19044.7846
- 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 11 23H2 affected >= 10.0.22631.0, < 10.0.22631.7711 fixed 10.0.22631.7711
- vendor:Windows 11 24H2 affected >= 10.0.26100.0, < 10.0.26100.9974 fixed 10.0.26100.9974
- vendor:Windows 11 25H2 affected >= 10.0.26200.0, < 10.0.26200.9974 fixed 10.0.26200.9974
- vendor:Windows 11 26H1 affected >= 10.0.28000.0, < 10.0.28000.3501 fixed 10.0.28000.3501
- vendor:Windows 11 26H2 affected >= 10.0.26300.0, < 10.0.26300.9974 fixed 10.0.26300.9974
- vendor:Windows Server 2025 affected >= 10.0.26100.0, < 10.0.26100.33822 fixed 10.0.26100.33822

## How to check

Run winver or [System.Environment]::OSVersion in PowerShell and compare the build (10.0.<build>.<revision>) with the fixed builds listed in the fix field; any build below its fixed revision is affected. Needs a local account to exploit.

## Fix

Install the November 2026 Windows cumulative update. Fixed builds: Win10 1607/Server 2016 10.0.14393.9688; Win10 1809/Server 2019 10.0.17763.9487; Win10 21H2 10.0.19044.7846; Win10 22H2 10.0.19045.7846; Server 2022 10.0.20348.5870; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974; Win11 25H2 10.0.26200.9974; Win11 26H1 10.0.28000.3501; Win11 26H2 10.0.26300.9974; Server 2025 10.0.26100.33822.
