# Windows: Function Discovery Resource Publication lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-119907 (this .md is for agents)

A pointer in the Windows Function Discovery Resource Publication component is dereferenced without validation. An authorized local attacker can use it to elevate privileges on the machine.

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

## How to check

Run winver or [System.Environment]::OSVersion / (Get-ComputerInfo).OsBuildNumber and compare the full build (e.g. 10.0.26100.xxxx) against the fixed builds in the fix field; anything lower is exposed. Also check on Server Core installations.

## Fix

Install the November 2026 cumulative update for your Windows version. Fixed builds: Win10 1607/Server 2016 10.0.14393.9688; Win10 1809/Server 2019 10.0.17763.9487; 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.
