Apple has released iOS 15.2.1 and iPadOS 15.2.1 to the public with minor bug fixes and other improvements.
Apple releases iOS 15.2.1 update
Both the iOS 15.2.1 and iPadOS 15.2.1 update are build number 19C63. They are available as an over-the-air download on compatible iPhone and iPad models. Users can get them through the software update mechanism in the Settings app.
Apple says that the release addresses a HomeKit denial of service issue, a problem where third-party CarPlay apps may lose touch sensitivity, and a bug where Messages may not load photos sent using an iCloud link.
The HomeKit DDoS attack was revealed by a researcher on January 1 and could be executed by entering a device name of over 500,000 characters. Devices that tried to load the device name could be placed into a reboot cycle and made unusable.
The previous update, iOS 15.2, was released on December 13, with legacy contacts and child protection features for iMessage.
