What it is

🚨 A buffer overflow in your NETGEAR Nighthawk WiFi6 Router could let attackers slide in and execute arbitrary code — a potential backdoor into your home network! 🔥 Think of it like a delivery service that accepts packages without checking the contents—an attacker could drop in anything they want. If your router doesn't inspect these incoming requests, they can easily take control. The consequences could be absolutely devastating! An attacker could gain unauthorized access, snoop on your network traffic, or even hijack your connected devices. This isn’t just a minor annoyance; it could lead to a full-blown compromise of your home network.
