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

Link for people: https://infrastack.ai/live/CVE-2026-95938 (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 attacker needs to be authorized on the machine first.

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

## How to check

- Check the Windows build with `winver` and compare it against the fixed build in Microsoft's security update guide for CVE-2026-95938
- Confirm the latest cumulative Windows update is installed with `wmic qfe list` or Settings > Windows Update

- 2026-11-10T20:23:39+00:00 analyst — MSRC page is JS-only (WebFetch empty), NVD page returned no content, MSRC CVRF feed too large to fetch; web-cli unavailable in this session. No primary source read, so no affected builds, KB or fixed version; nothing verified. Needs MSRC entry via browser-cli or Update Guide to settle fix and builds. Left severity, tags and summary as triage had them.

## From the sources

Heap-based buffer overflow in Windows Graphics Kernel allows an authorized attacker to elevate privileges locally.
