# Windows Graphics Kernel: use-after-free lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-94519 (this .md is for agents)

A use-after-free bug in the Windows Graphics Kernel lets an attacker who already has a local account raise their privileges. The sources do not say which Windows builds are affected or what fix Microsoft has shipped.

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

## Affected

- 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 PowerShell [System.Environment]::OSVersion.Version / (Get-ComputerInfo).OsBuildNumber and compare the full build (e.g. 10.0.26100.xxxx) with the fixed builds: Win11 24H2 < 10.0.26100.9974, 25H2 < 10.0.26200.9974, 26H1 < 10.0.28000.3501, 26H2 < 10.0.26300.9974, Server 2025 (incl. Server Core) < 10.0.26100.33822 are vulnerable. Other Windows versions are not listed by Microsoft.

## Fix

Install the November 2026 Windows cumulative update: Windows 11 24H2 build 10.0.26100.9974 or later, 25H2 10.0.26200.9974, 26H1 10.0.28000.3501, 26H2 10.0.26300.9974, Windows Server 2025 10.0.26100.33822. KB numbers not read.
