Apple has published security updates for older iPhones and iPads to backport patches released one week ago, addressing two zero-day vulnerabilities exploited in attacks.
The first zero-day is a privilege escalation vulnerability caused by a weakness in the XNU kernel that can let local attackers elevate privileges on vulnerable iPhones and iPads.
Apple has now also fixed the issue in iOS 16.7.1 and iPadOS 16.7.1 with improved checks, but it has yet to reveal who discovered and reported the flaw.
