Gamers Nexus reports LG smart TVs sweep the local network and capture microphone audio in standby

Summary: Notebookcheck reports on a Gamers Nexus investigation that describes LG smart TVs enumerating other devices on the local network and logging microphone audio with the screen off, on retail LG OLED sets including the G5 running webOS, with the full affected model range not yet known. Notebookcheck states the set kept saving voice input locally after the team disconnected it from Ethernet and uploaded the stored files once network access was restored, and that the collected data feeds LG Ad Solutions, which states access to 363 million secondary addressable devices in the US against LG's claimed 216 million smart TV sales globally. This run could not read the 135-minute video itself, so every figure in the account comes from Notebookcheck rather than from the recording, and LG has made no statement.
Why it matters: The reported behavior is a shipped consumer device acting as a network scanner on the LAN it is plugged into and holding audio through a network outage to upload afterwards, on a platform whose ad arm counts 363 million addressable US devices.
Follow-up: An LG statement, the webOS remote code execution findings once disclosure closes, and independent confirmation of the network sweep and the standby audio capture.
