iOS 15.2.1 and iPadOS 15.2.1 are both new releases of the iOS operating system, and they include a number of new features and improvements. Here are some of the most important changes in these releases:

  • A new security feature called “Find My iPhone” has been added to iOS, which allows users to locate their device if it is lost or stolen. This feature is available through the “Settings” app on your device, and it can be turned on or off through this setting.
  • A new “Do Not Disturb” mode has been added to iOS, which helps you keep your device screen off while you sleep or work. This mode is available through the “Settings” app on your device, and it can be turned on or off through this setting.
  • A number of bug fixes have been included in iOS 15.2.1 and iPadOS 15.2.1, including a fix for an issue that could cause crashes when using certain apps such as Safari and Photosynthesis; a fix for an issue that could prevent users from being able to use certain features of Apple’s AirPlay 2 protocol; a fix for an issue that could prevent users from being able to use certain AirPlay 2 devices; and a fix for an issue that could prevent users from being able to use certain Bluetooth devices with their iOS devices

There’s a new version of iOS and iPadOS out right now. Version 15.2.1 of Apple’s mobile operating systems doesn’t change much, but you’re still going to want to download it as soon as possible to patch any security holes.

The update mainly aims to fix some minor but annoying bugs and a big HomeKit denial of service vulnerability.

Starting with the bugs, Apple fixed a CarPlay bug that could cause third-party apps to ignore user input. I’ve been dealing with the bug personally as an avid CarPlay user, so I’m excited to get this update running so I can end the frustration.

Another patch will fix an issue that saw Messages not loading photos sent using an iCloud Link. This is a massive fix for anyone who keeps their photos in the cloud and wants to have an easy way to share them.

Regarding the security issue, Apple describes it by saying, “Processing a maliciously crafted HomeKit accessory name may cause a denial of service.”

Security researcher Trevor Spiniolas describes the issue in more detail:

With the update, that HomeKit hole is closed, which is one fewer security issue for you to worry about. If you own an iPhone or iPad, make sure to download version 15.2.1 to fix those pesky bugs and close that significant security hole.
