CVE-2024-54503

Persistent ringing via inconsistent mute state

Published Dec 11, 2024 · Updated Apr 2, 2026

UI inconsistency in Audio in Apple iOS and iPadOS before 18.2 allows ringing calls to remain audible after a mute action. The ringing-call mute control can diverge from the underlying Audio state because state management does not consistently enable mute. The condition requires a user to invoke mute while a call is ringing; the bounded consequence is continued ringing rather than data access or code execution.
