⚡ Tenda AX-3 users, listen up! A sneaky stack overflow in the `fromAdvSetMacMtuWan` function could send your network crashing down with just a crafted request! 🔥 Think of it like filling a balloon until it pops. With a small poke — or in this case, a malicious request — your entire system could deflate, leaving everyone disconnected. An attacker could trigger this vulnerability, leading to a Denial of Service (DoS) that disrupts your network connectivity. Imagine all your devices going offline, unable to communicate, which is absolutely devastating for any home or office environment! 🤯
