⚠️ A stack overflow vulnerability lurks in the Tenda O6 firmware, hiding like a sneaky gremlin in a tech closet! Think of it as a crowded elevator that suddenly overloads; too many people pushing too hard can cause it to malfunction and stop working completely. In this case, the overloaded function can make the router go haywire! An attacker could exploit this stack overflow to crash the device, disrupting your network and leaving you in the digital dark. While it may not lead to a total takeover, it could still leave your router vulnerable while it’s down, affecting all devices connected to it.
