CVE-2021-1872

A logic issue was addressed with improved state management.

MEDIUM 4.3EPSS 1.04%

Does this matter?

Lower severity and a low EPSS score (1.04%). Track it; it rarely justifies an emergency change on its own.

Description

A logic issue was addressed with improved state management. This issue is fixed in iOS 14.5 and iPadOS 14.5, watchOS 7.4, macOS Big Sur 11.3. Muting a CallKit call while ringing may not result in mute being enabled.
