iOS 16.3.1, iPadOS 16.3.1, macOS 13.2.1 Ventura, watchOS 9.3.1, tvOS 16.3.2, and HomePod Software 16.3.2 Fix Bugs and Security Vulnerabilities

Apple has once again pushed out updates to its entire family of operating systems, fixing bugs and addressing security vulnerabilities. Because one of these vulnerabilities—a bug in WebKit that could allow maliciously crafted Web content to execute code—is being actively exploited in the wild, we recommend installing all these updates immediately.

Details, such as they are, include:

  • iOS 16.3.1: Apple says this update fixes a problem with iCloud settings displaying incorrectly or being unresponsive if apps are using iCloud, addresses an issue that prevented Siri requests for Find My from working, and improves Crash Detection on the iPhone 14 and iPhone 14 Pro models. With luck, Crash Detection will now stop triggering false alarms for skiers. iOS 16.3.1 also plugs two security vulnerabilities: the actively exploited WebKit vulnerability and another in the kernel.
  • iPadOS 16.3.1: Unsurprisingly, iPadOS 16.3.1 gets the same bug and security fixes as iOS 16.3.1, minus the Crash Detection optimizations.
  • macOS 13.2.1 Ventura: Apple doesn’t share any details about bugs fixed in Ventura but calls out three security fixes, the two previously mentioned and another in Shortcuts.
  • watchOS 9.3.1: Apple hasn’t published release or security notes for watchOS 9.3.1 yet, but it’s a safe bet they won’t include anything surprising.
  • tvOS 16.3.2: Nothing to see here—Apple merely says this update includes “general performance and stability improvements” and hasn’t yet published security notes. tvOS 16.3.1, which Apple quietly released a week ago, had the same release notes.
  • HomePod Software 16.3.2: Apple didn’t describe last week’s HomePod Software 16.3.1, but 16.3.2 includes a fix for a bug where asking Siri to control smart home accessories could fail, along with general performance and stability improvements. There are no security notes for this update.
