# Windows Broadcast DVR User Service heap overflow and race condition lets local users gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-94529 (this .md is for agents)

Heap-based buffer overflow (CWE-122, with a race condition, CWE-362) in the Windows Broadcast DVR User Service. A local attacker with a low-privilege account can raise privileges. CVSS 7.0, attack complexity high, no exploitation known (E:U). Fixed in the November 2026 updates.

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

## Affected

- vendor:Windows 10 1809 affected < 10.0.17763.9487 fixed 10.0.17763.9487

## How to check

Run winver or [System.Environment]::OSVersion.Version in PowerShell and compare the full build number (e.g. 10.0.26100.xxxx) with the fixed build for your release. A build below the fixed one is exposed.

## Fix

Install the November 2026 Windows cumulative update for your release. Fixed builds per Microsoft's CVE record as mirrored by OpenCVE: Win10 1809 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.
