What it is

⚠️ A sneaky stack overflow lurks in the TOTOLINK N600R, and it could let attackers poke their fingers into places they shouldn’t! Think of it as a crowded elevator that suddenly accepts too many passengers without checking who or what’s inside — before you know it, it jams and could malfunction, potentially spilling its secrets. In this case, an attacker could exploit the stack overflow to manipulate system processes, leading to unexpected behaviors or even crashes. If they gain control, they could access sensitive information or disrupt the network. Yikes!
