CVE-2022-22588Public exploit

Persistent device hang via oversized accessory name

Published Mar 18, 2022 · Updated Aug 3, 2024

Resource exhaustion in HomeKit in Apple iOS and iPadOS before 15.2.1 allows attackers to hang devices via a crafted accessory name. HomeKit accepts an extremely long accessory-name string without adequate length validation and repeatedly loads it from synchronized Home data, exhausting resources. The device must load the crafted name, including after an accepted malicious Home invitation; the interface can remain unusable across reboots.
