# Windows Broadcast DVR service: memory bug lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-112761 (this .md is for agents)

A use-after-free flaw in the Windows Broadcast DVR User Service lets an attacker who already has a local account elevate their privileges. The sources do not describe the exact trigger, and the CVSS score is 7.0.

_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).OsBuildRevision and compare the full build (e.g. 10.0.26100.xxxx) with the fixed build for your version. Below it means unpatched. Service state: Get-Service BcastDVRUserService_* (per-user service). Whether it is on by default is not confirmed.

## Fix

Install the November 2026 Windows cumulative update that brings your build to at least the fixed build for your version (per the CVE record mirror): 1809/Server 2019 10.0.17763.9487; 10 21H2 10.0.19044.7846; 10 22H2 10.0.19045.7846; 11 23H2 10.0.22631.7711; 11 24H2 10.0.26100.9974; 11 25H2 10.0.26200.9974; 11 26H1 10.0.28000.3501; 11 26H2 10.0.26300.9974. KB number not confirmed; look it up in the MSRC entry for this CVE.
