# Windows Client for NFS: race condition lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-118138 (this .md is for agents)

Windows Client for NFS has a race condition in how it handles a shared resource, so a local attacker who is already authorized can elevate their privileges. The sources rate it high (CVSS 7.8) and do not report active exploitation.

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

## How to check

- Check whether the Windows Client for NFS feature is installed and enabled on the machine (unknown from the sources for exact commands)
- Compare the Windows build against Microsoft's security update guide for this CVE (unknown from the sources)

## Timeline

## From the sources

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Client for NFS allows an authorized attacker to elevate privileges locally.
