# Windows kernel-mode drivers: untrusted pointer lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-96139 (this .md is for agents)

A flaw in Windows kernel-mode drivers dereferences an untrusted pointer. An attacker who already has a local account can use it to elevate privileges.

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

## Affected

- microsoft:Windows 11 24H2 affected < 10.0.26100.9974 fixed 10.0.26100.9974
- microsoft:Windows 11 25H2 affected < 10.0.26200.9974 fixed 10.0.26200.9974
- microsoft:Windows 11 23H2 affected < 10.0.22631.7711 fixed 10.0.22631.7711
- microsoft:Windows 10 22H2 affected < 10.0.19045.7846 fixed 10.0.19045.7846
- microsoft:Windows Server 2025 affected < 10.0.26100.33822 fixed 10.0.26100.33822
- microsoft:Windows Server 2022 affected < 10.0.20348.5870 fixed 10.0.20348.5870
- microsoft:Windows Server 2019 affected < 10.0.17763.9487 fixed 10.0.17763.9487
- microsoft:Windows Server 2016 affected < 10.0.14393.9688 fixed 10.0.14393.9688

## How to check

Run winver or 'cmd /c ver' on each machine and compare the build number (10.0.<build>.<revision>) to the fixed builds in the fix field. Lower revision means exposed.

## Fix

Install the November 2026 Windows cumulative update that raises the build to at least: 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 10.0.26100.9974; 25H2 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.
