Although this vulnerability, reported on CyberSecurityNews, sounds bad (it allows attackers to remotely execute code on your computer without you clicking anything), it will not affect most users, and Microsoft has already issued a patch.

The issue only affects the IPv6 protocol, and only on Windows computers. Many users still do not have IPv6 (virtually every computer supports IPv6, but not all ISPs support the protocol). You are only at risk if your Windows machine has an exposed (to the Internet) IPv6 address. Modern Internet modems have a firewall to prevent external access to your devices IPv6 addresses unless you explicitly expose them, which you would only do if you are offering services like a web-server or an FTP server to Internet users. If you are, you should apply the patch immediately.
