⚠️ A sneaky stack overflow lurks in Tenda AC1206's DHCP client function! Just a bit of crafted input can lead to some chaos. 🔥 Think of it like overstuffing a suitcase that’s already full; eventually, it bursts open and spills everything out. In this case, a carefully crafted input can overflow the stack and cause unpredictable behavior. An attacker could exploit this stack overflow to crash the device, potentially leading to downtime and loss of connectivity. While it’s not known to be widely exploited yet, having your device unexpectedly reboot could be a real inconvenience for users relying on it.
