Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

A logic issue was addressed with improved checks. This issue is fixed in iOS 26.3 and iPadOS 26.3. A user with Live Caller ID app extensions turned off could have identifying information leaked to the extensions.
