# Windows Phone Service: null pointer flaw lets local users gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-96107 (this .md is for agents)

A null pointer dereference in the Windows Phone Service lets a user who already has authorized local access raise their privileges. The sources give no detail beyond that description.

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

## Affected

- microsoft:Windows 10 Version 1607 affected >= 10.0.14393.0, < 10.0.14393.9688 fixed 10.0.14393.9688

- microsoft:Windows 11 Version 25H2 affected >= 10.0.26200.0, < 10.0.26200.9974 fixed 10.0.26200.9974
- microsoft:Windows 11 Version 26H1 affected >= 10.0.28000.0, < 10.0.28000.3501 fixed 10.0.28000.3501
- microsoft:Windows 11 Version 26H2 affected >= 10.0.26300.0, < 10.0.26300.9974 fixed 10.0.26300.9974

## How to check

Run winver or [Environment]::OSVersion in PowerShell and compare the build (10.0.x.y) with the fixed builds listed; below the fixed build means exposed.

## Fix

Install the November 2026 Windows cumulative update that moves the build to at least the fixed build for your version (see products); KB numbers unknown, confirm in MSRC Update Guide.
