# Windows: Internet Connection Sharing use-after-free lets local users gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-119859 (this .md is for agents)

A use-after-free bug in Windows Internet Connection Sharing (ICS) lets an authorized local user elevate their privileges. An attacker who already has a low-privilege account on the machine can gain higher rights.

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

## How to check

- Check whether the Internet Connection Sharing service (SharedAccess) is running on Windows machines with `sc query SharedAccess`
- Confirm the Windows build and update level with `winver` or `Get-ComputerInfo`
