Apple has fixed a security vulnerability in iOS and iPadOS that could be exploited via HomeKit to launch persistent denial of service (DoS) attacks.

The technology giant released iOS 15.2.1 and iPadOS 15.2.1 on Wednesday to patch the so-called “doorLock” flaw, which was disclosed earlier this month by security researcher Trevor Spiniolas. The bug affects iPhones and iPads running iOS 14.7 through iOS 15.2 and is triggered via HomeKit, Apple’s smart home platform that lets Apple users configure, communicate with, and control their smart home devices
