Apple has credited Bill Marczak of The Citizen Lab at The University of Toronto's Munk School, and Maddie Stone of Google's Threat Analysis Group, for discovering and reporting the security vulnerabilities to Apple.


CVE-2023-41992 tracks the first security issue, which affects a Kernel level flaw in the operating systems, which could have allowed an attacker to elevate their privileges.
