What it is

โš ๏ธ Watch out for the lurking buffer overflow in Tenda AC6 firmware! This vulnerability can send your router into a tailspin just by feeding it the wrong input. ๐Ÿ”ฅ Think of it like overfilling a soda can โ€” if it gets too full, the contents spill everywhere, causing a mess. In this case, too much input in the buffer can overflow and disrupt the router's normal function, just like that can exploding in your bag. If exploited, this vulnerability might allow an attacker to crash the device or potentially execute malicious code. Imagine your router throwing a fit and cutting off your internet access, or worse, allowing someone to hijack your network!
