Apple Ships Emergency iOS Security Patches
Apple pushed security updates for iOS and iPadOS 15 and 16 on March 12 to address an active exploit called Coruna. The updates target older iPhone and iPad models that can't run the latest iOS 17 versions.
The company didn't provide detailed technical information about the Coruna exploit in its brief announcement. Apple typically reserves such updates for serious security flaws that pose immediate risks to users.
