# Windows DNS: out-of-bounds read lets a network attacker leak data

Link for people: https://infrastack.ai/live/CVE-2026-96972 (this .md is for agents)

Windows DNS reads memory past the end of a buffer when handling certain network requests. An unauthorized attacker on the network can use this to disclose information from the server.

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

## How to check

- Check whether the server runs the DNS Server role, for example with `Get-WindowsFeature DNS` in PowerShell.
- Compare the installed Windows build against the Microsoft update for CVE-2026-96972; the affected builds are unknown from the sources.

## Timeline

- 2026-11-10T19:44:15+00:00 analyst — MSRC advisory and NVD page not retrievable (empty results); no affected builds or KB found. Search hits were other DNS CVEs, not this id. Nothing verified; fix left unknown. Revisit when MSRC page is readable.

## From the sources

Out-of-bounds read in Windows DNS allows an unauthorized attacker to disclose information over a network.
