As usual for Apple patches, vulnerabilities tend to affect all/most Apple operating systems. One notable security issue that was addressed, but is not listed here, is the “USB accessory unlock” issue. This allowed systems like Greylock to unlock phones by brute forcing the passcode via the lightning port / USB. iOS 11.4.1 only allows USB devices to connect within 1 hour after the phone/tablet is locked. This is enabled by default but can be disabled by the user. OS X also fixes the latest versions of Spectre.
