# Windows Bind Filter Driver: weak authentication lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-70182 (this .md is for agents)

The Windows Bind Filter Driver has weak authentication, so a user already authorized on the machine can elevate their privileges. An attacker who has a local account can gain higher rights on that Windows system.

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

## How to check

Unknown until Microsoft lists affected builds. Check the Security Update Guide entry for CVE-2026-70182, then compare the installed cumulative update (Settings > Windows Update > Update history, or Get-HotFix) against the KB it names. bindflt.sys is present on supported Windows 10/11 and Server by default, so assume it is installed.

- 2026-11-10T21:13:37+00:00 analyst — Could not read NVD or MSRC pages (empty/JS-only); no affected builds, KB or fix found for this CVE. Nothing verified. Sibling Bind Filter CVEs exist (bindflt.sys, Windows 10/11, Server 2022/2025) but are not this id. Revisit when MSRC fills in the entry.

## From the sources

Weak authentication in Windows Bind Filter Driver allows an authorized attacker to elevate privileges locally.
