# Windows 11 kernel: incorrect authorization lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-95988 (this .md is for agents)

A flaw in the Windows kernel lets an attacker who already has a local account raise their privileges. Successful exploitation gives the attacker control beyond what their account should allow.

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

## Affected

- vendor:Windows 11 24H2 affected >= 10.0.26100.0, < 10.0.26100.9974 fixed 10.0.26100.9974
- vendor:Windows 11 25H2 affected >= 10.0.26200.0, < 10.0.26200.9974 fixed 10.0.26200.9974
- vendor:Windows 11 26H1 affected >= 10.0.28000.0, < 10.0.28000.3501 fixed 10.0.28000.3501
- vendor:Windows 11 26H2 affected >= 10.0.26300.0, < 10.0.26300.9974 fixed 10.0.26300.9974

## How to check

Run winver (or [System.Environment]::OSVersion) and compare the build with the fixed build for your Windows 11 version: 24H2 fixed at 10.0.26100.9974, 25H2 at 10.0.26200.9974, 26H1 at 10.0.28000.3501, 26H2 at 10.0.26300.9974. Any lower build is affected. The KB number is unknown until the MSRC page is read.

## Fix

Install the Windows update that brings the build to 10.0.26100.9974 (24H2), 10.0.26200.9974 (25H2), 10.0.28000.3501 (26H1) or 10.0.26300.9974 (26H2) or later. KB number unknown.
