# Windows DNS: uninitialized memory lets an attacker run code remotely

Link for people: https://infrastack.ai/live/CVE-2026-113855 (this .md is for agents)

A flaw in the Windows DNS server leaves a resource uninitialized before use, so memory contents can be misused. An unauthorized attacker on the adjacent network could execute code.

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

## How to check

- Confirm whether the host runs the DNS Server role on Windows (for example, check the DNS Server service in Services).

## Timeline

## From the sources

Use of uninitialized resource in Windows DNS allows an unauthorized attacker to execute code over an adjacent network.
