# Windows USB Scanner Driver: heap overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-119876 (this .md is for agents)

A heap overflow in the Windows USB Scanner Driver lets a local, already-authorized user reach SYSTEM. Microsoft rates it CVSS 7.0, needs winning a race, not exploited or publicly disclosed (Exploitation Less Likely). Fixed build numbers were not retrieved.

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

## How to check

Check whether the Microsoft November 2026 cumulative update for your Windows build is installed (Settings > Windows Update > Update history, or Get-HotFix in PowerShell). Look up your build under CVE-2026-119876 in the MSRC Security Update Guide for the exact KB; I could not read it.
