The first issue involved the potential for an application "to execute arbitrary code with kernel privileges," according to Apple’s security updates website.
A kernel is the central component of a computer’s operating system and it manages all of the operations and hardware. The kernel acts as a bridge between "applications and data processing performed at hardware level using inter-process communication and system calls," according to Geeksforgeeks.org.
Here are the specifics that Apple has provided on the security update: The second security fix was in WebKit, the browser engine that powers Safari and all third-party browsers on iOS.
