# Windows Audio Service: out-of-range pointer lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-105541 (this .md is for agents)

Windows Audio Service mishandles a pointer offset, so an attacker who already has a local account can raise their privileges. The NVD entry gives a CVSS score of 7.8 (high) and reports no exploitation in the wild.

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

## How to check

- Check the installed Windows build with `winver` and compare it with the fixed build in Microsoft's advisory, which the sources do not name.
- Confirm the Windows Audio service is running with `sc query Audiosrv`.

## From the sources

Use of out-of-range pointer offset in Windows Audio Service allows an authorized attacker to elevate privileges locally.
