# Windows Overlay Filter: integer overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-112760 (this .md is for agents)

Integer overflow in the Windows Overlay Filter (WOF) driver lets a local attacker raise privileges. Microsoft rates it High (CVSS 7.8, vector AV:L/AC:L/PR:N/UI:R). It was fixed in the November 2026 Patch Tuesday updates (10 Nov 2026). No exploitation or public PoC found.

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

## Affected

- vendor:Windows 10 / 11 / Server (Overlay Filter) affected below the November 2026 build for each release fixed see fix field

## How to check

Run winver or PowerShell [System.Environment]::OSVersion and compare the full build number (e.g. 10.0.26100.xxxx) with the fixed builds listed. Anything below the fixed build is exposed. Confirm the exact KB on the MSRC page.

## Fix

Install the November 2026 cumulative update. Fixed builds per Microsoft CNA data (via aggregator, unconfirmed on MSRC): Win10 1607/Server 2016 10.0.14393.9688; 1809/Server 2019 10.0.17763.9487; Win10 21H2 10.0.19044.7846; 22H2 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 and 25H2 10.0.26100.9974 / 10.0.26200.9974; 26H1 10.0.28000.3501; 26H2 10.0.26300.9974; Server 2022 10.0.20348.5870; Server 2025 10.0.26100.33822.
