# Windows: use-after-free in SSDP discovery lets attackers run code remotely

Link for people: https://infrastack.ai/live/CVE-2026-118145 (this .md is for agents)

A use-after-free bug in the Windows Function Discovery SSDP Provider lets an unauthorized attacker on the adjacent network run code on the machine. The sources give a CVSS score of 7.5 and do not describe any exploitation in the wild.

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

## How to check

Unknown until MSRC lists affected builds. Meanwhile: check whether the SSDP Discovery / Function Discovery services (SSDPSRV, FDPHost, fdPHost) are running on machines (Get-Service SSDPSRV,fdPHost) and apply the November 2026 Windows cumulative update.
