# Windows Deployment Services: heap overflow lets an authorized user run code remotely

Link for people: https://infrastack.ai/live/CVE-2026-105558 (this .md is for agents)

Windows Deployment Services has a heap-based buffer overflow that lets an authorized attacker run code over the network. The attacker needs valid access to the service first, and the advisory does not state a fixed version.

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

## How to check

- Check whether the Windows Deployment Services role is installed on the server (unknown if the sources give a command)

Heap-based buffer overflow in Windows Deployment Services allows an authorized attacker to execute code over a network.
