# Windows Graphics Kernel: heap overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-95922 (this .md is for agents)

A heap-based buffer overflow in the Windows Graphics Kernel lets an attacker who already has a local account raise their privileges. The flaw is local only, so an attacker needs to be able to run code on the machine first.

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

- microsoft:Windows Server 2025 affected < 10.0.26100.33822 fixed 10.0.26100.33822

## How to check

Run winver or PowerShell [System.Environment]::OSVersion.Version (or cmd 'ver') and compare the full build.revision with the fixed build for your Windows version; lower means exposed.

## Fix

Install the November 2026 Windows cumulative update that raises the OS build to at least the fixed build for your version (e.g. Windows 11 24H2/25H2: 10.0.26100.9974/26200.9974; Windows 10 22H2: 10.0.19045.7846; Server 2022: 10.0.20348.5870; Server 2025: 10.0.26100.33822).
