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:
When the name of a HomeKit device is changed to a large string (500,000 characters in testing), any device with an affected iOS version installed that loads the string will be disrupted, even after rebooting. Restoring a device and signing back into the iCloud account linked to the HomeKit device will again trigger the bug.
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.
