What it is

⚠️ An uncaught exception could lead to a surprising leak of uninitialized heap data in Modem! This means no user interaction is needed for attackers to disrupt your service. 🔥 Think of it like a restaurant where the chef accidentally serves a dish that hasn't been fully prepped — some ingredients are raw and untested. This oversight can leave diners feeling queasy, just like your users may feel when hit with a denial of service! If a user connects to a rogue base station, this could lead to a remote denial of service attack, where legitimate users are kicked out without warning. Imagine everyone trying to enter a concert, only to find the doors suddenly locked — frustrating and infuriating!
