Apple released a surprise security patch for the iPhone on Monday, updating the smartphone's software to iOS 16.4.1a -- but the company offered exactly no other information about the security vulnerability.
The patch is part of a new protocol from the company called Rapid Security Response, and after testing them in the beta update channels, this type of update are now slowly rolling out to devices running iOS 16.4.1, iPadOS 16.4.1, and macOS 13.3.1.
