Apple has released security updates to address a persistent denial of service (DoS) dubbed doorLock that would altogether disable iPhones and iPads running HomeKit on iOS 14.7 and later.

HomeKit is an Apple protocol and framework that allow iOS and iPadOS users to discover and control smart home appliances on their network.

As the company explained in a security advisory issued today, the doorLock vulnerability tracked as CVE-2022-22588 will crash affected iOS and iPadOS devices when processing maliciously crafted HomeKit accessory names.

Apple has addressed this severe resource exhaustion issue in iOS 15.2.1 and iPadOS 15.2.1 by adding improved input validation which no longer allows attackers to disable vulnerable devices.

Devices that received security updates today include iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation).
