# Windows: heap overflow in graphics platform lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-118229 (this .md is for agents)

A heap-based buffer overflow in the Windows Advanced Rasterization Platform lets an attacker who already has a local account raise their privileges. The sources do not describe a remote trigger.

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

## How to check

Unknown. Look up CVE-2026-118229 in the Microsoft Security Update Guide for your Windows build and KB, then compare it with the installed build (winver or Get-HotFix).

- 2026-11-10T23:17:00+00:00 analyst https://nvd.nist.gov/vuln/detail/CVE-2026-118229 — Could not read the MSRC Update Guide entry (JS-only; web-cli and the CVRF API returned nothing useful; the API only confirms it is in the November 2026 release). Only NVD text is available, so affected builds and KB numbers are unknown. Nothing verified. Not marked exploited; no PoC found.
