# Windows Filter Manager: use-after-free lets a local user gain SYSTEM-level privileges

Link for people: https://infrastack.ai/live/CVE-2026-113755 (this .md is for agents)

A use-after-free bug in the Windows Filter Manager driver lets a user who already has local access corrupt memory and raise their privileges. The sources give no further detail on the exploit path.

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

## Affected

- vendor:Windows 10 affected 1607 < 10.0.14393.9688; 1809 < 10.0.17763.9487; 21H2 < 10.0.19044.7846; 22H2 < 10.0.19045.7846 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846
- vendor:Windows 11 affected 23H2 < 10.0.22631.7711; 24H2 < 10.0.26100.9974; 25H2 < 10.0.26200.9974; 26H1 < 10.0.28000.3501; 26H2 < 10.0.26300.9974 fixed 10.0.22631.7711, 10.0.26100.9974, 10.0.26200.9974, 10.0.28000.3501, 10.0.26300.9974
- vendor:Windows Server affected 2016 < 10.0.14393.9688; 2019 < 10.0.17763.9487; 2022 < 10.0.20348.5870; 2025 < 10.0.26100.33822 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.20348.5870, 10.0.26100.33822

## How to check

On each Windows host run winver or [System.Environment]::OSVersion.Version (PowerShell) and compare the full build (e.g. 10.0.19045.xxxx) with the fixed builds in the fix field; a build below the fixed one is exposed.

## Fix

Install the November 2026 Windows cumulative update that brings the build to at least: 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; Server 2022 10.0.20348.5870; 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 2025 10.0.26100.33822.
