# Windows DNS: out-of-bounds read leaks memory to network attackers

Link for people: https://infrastack.ai/live/CVE-2026-108425 (this .md is for agents)

Windows DNS reads memory past the end of a buffer when handling a crafted request. An unauthenticated attacker on the network can read that memory and disclose information.

_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 (`Get-WindowsFeature DNS` in PowerShell)
- Check the installed Windows build against Microsoft's update history (`winver`)

## Timeline

- 2026-11-10T19:24:23+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-108425

## From the sources

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