⚡ A single oversize input to the schedEndTime parameter can crash the whole Tenda AC10U router! Just like a restaurant overwhelmed by a party of too many guests, this stack overflow could leave your device gasping for air! Think of your router as a busy restaurant kitchen. If it tries to juggle more orders than it can handle, it can crash, leaving diners (or in this case, devices) waiting in hungry frustration. That's exactly what a stack overflow does here — it overwhelms the router's ability to process requests! If exploited, an attacker could effectively cause a denial of service, shutting down your Wi-Fi and leaving all your connected devices offline. Imagine being cut off from the internet when you need it most! That's a serious inconvenience and could lead to chaos in your digital life.
