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

Link for people: https://infrastack.ai/live/CVE-2026-95991 (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 whether it is exploited in the wild.

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

## How to check

- Open Microsoft's Security Update Guide entry for CVE-2026-95991, find your Windows version in the affected products table and note the fixed build/KB. Run winver (or Get-HotFix) and compare; if the KB is installed or your build is at/above the fixed one, you are patched.

## Timeline

- 2026-11-10T20:13:23+00:00 analyst — Could not read Microsoft's advisory: MSRC page is JS-only (web-cli empty), CVRF API 404/too large, browser-cli 402 credits. Only NVD data (CVSS 7.8 AV:L/PR:L, vendor-scored) is known; builds, KB and exploitation status unknown. Nothing verified. Needs the MSRC entry read for builds/KB.

## From the sources

Use after free in Windows Graphics Kernel allows an authorized attacker to elevate privileges locally.
