# Windows Audio Service: use-after-free lets local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-119895 (this .md is for agents)

Use-after-free in the Windows Audio Service lets an attacker with a low-privilege local account elevate privileges (CVSS 7.0, AV:L/AC:H/PR:L). Microsoft lists Windows 11 23H2, 24H2, 25H2, 26H1, 26H2 and Windows Server 2025 (including Server Core) as affected below the fixed builds. Trigger details are not published.

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

## Affected

- vendor:Windows 11 23H2 affected < 10.0.22631.7711 fixed 10.0.22631.7711
- vendor:Windows 11 24H2 affected < 10.0.26100.9974 fixed 10.0.26100.9974
- vendor:Windows 11 25H2 affected < 10.0.26200.9974 fixed 10.0.26200.9974
- vendor:Windows 11 26H1 affected < 10.0.28000.3501 fixed 10.0.28000.3501
- vendor:Windows 11 26H2 affected < 10.0.26300.9974 fixed 10.0.26300.9974
- vendor:Windows Server 2025 affected < 10.0.26100.33822 fixed 10.0.26100.33822

## How to check

Run winver or PowerShell [System.Environment]::OSVersion.Version and compare the build (10.0.<build>.<revision>) with the fixed builds: 23H2 22631.7711, 24H2 26100.9974, 25H2 26200.9974, 26H1 28000.3501, 26H2 26300.9974, Server 2025 26100.33822. Anything lower is affected. Source: NVD record with Microsoft CNA data; confirm on the MSRC page.

## Fix

Install the November 2026 Windows cumulative update bringing the build to at least: Win11 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, Server 2025 10.0.26100.33822. KB numbers unknown.
