The Wi-Fi network name bug that was found to completely disable an iPhone’s networking functionality had remote code execution capabilities. Apple is expected to push a patch for the bug in its iOS 14.7 update, which is currently available to developers and public beta testers. The issue is remediable by resetting the network settings (Settings > General > Reset > Reset Network Settings) It’s also a zero-click vulnerability in that it allows the threat actor to infect a device without requiring any user interaction.
