# Windows TCP/IP: double free lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-96969 (this .md is for agents)

A double free bug in the Windows TCP/IP networking stack lets an attacker who already has a local account raise their privileges. The sources do not say which Windows versions are affected or what fix Microsoft shipped.

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

## How to check

Unknown: affected Windows builds not read from a primary source. Look up CVE-2026-96969 in the Microsoft Security Update Guide, then compare your build (winver) with the listed KB and confirm it is installed (Get-HotFix).

## Timeline

- 2026-11-10T19:50:23+00:00 analyst — Could not read MSRC entry (JS-only page, browser session died; NVD page gave no details). No affected builds or KB/fix confirmed; nothing verified. Revisit when MSRC text is reachable. X/search not tried.

## From the sources

Double free in Windows TCP/IP allows an authorized attacker to elevate privileges locally.
