# Windows: use-after-free in Device Association Service allows local privilege escalation

Link for people: https://infrastack.ai/live/CVE-2026-119874 (this .md is for agents)

A use-after-free in the Windows Device Association Service lets a user with low-privilege local access gain higher privileges (CVSS 7.0, attack complexity high). Microsoft lists fixed builds for Windows 10, 11 and Server 2022/2025. No exploitation or public PoC found.

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

## How to check

Run winver or 'cmd /c ver' and compare the full build number (10.0.x.y) with the fixed build for your Windows version; lower means exposed.

## Fix

Install the November 2026 Windows cumulative update that brings your build to at least the fixed build: Win10 21H2 10.0.19044.7846, Win10 22H2 10.0.19045.7846, Win11 23H2 10.0.22631.7711, Win11 24H2 10.0.26100.9974, Win11 25H2 10.0.26200.9974, Win11 26H1 10.0.28000.3501, Win11 26H2 10.0.26300.9974, Server 2022 10.0.20348.5870, Server 2025 10.0.26100.33822.
