# Windows Search Component: out-of-bounds write lets a network attacker run code

Link for people: https://infrastack.ai/live/CVE-2026-116928 (this .md is for agents)

A memory-corruption bug in the Microsoft Windows Search Component lets an unauthorized attacker write past a buffer. The sources say this allows code execution over a network.

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

## Affected

- vendor:Microsoft Windows Search affected range not listed fixed no fixed version listed

## How to check

unknown: MSRC has not been readable yet. Once the update guide lists KBs, compare the installed build (winver, or Get-HotFix) against the fixed build. Windows Search service (WSearch) status: Get-Service WSearch.

## Timeline

- 2026-11-10T19:32:56+00:00 analyst — MSRC page is JS-only (empty via web-cli); no build list, fix or KB found in NVD or searches published hours ago. Nothing verified. Revisit once MSRC lists builds.

## From the sources

Out-of-bounds write in Microsoft Windows Search Component allows an unauthorized attacker to execute code over a network.
