What Is the C1 Modem Vulnerability?
The C1 modem in the iPhone 16e is responsible for managing cellular connections, including phone calls, text messages, and data transfer. The vulnerability, as outlined in Apple’s security document, could have allowed attackers in a "privileged network position" to intercept and manipulate communications.

These patches are essential for maintaining the security and stability of your iPhone, particularly if you rely on features like FaceTime and Notes. None of the flaws were actively exploited, but that doesn’t mean you should delay updating your device.
