A security vulnerability in WebKit could allow attackers to remotely execute code through malicious web pages. The issue has been referenced as CVE-2023-23529.

A second security bug in iOS 16.3.1, iPadOS 16.3.1 and macOS 13.2.1 was related to the Kernel in the operating systems. Hackers could use an app with kernel privileges to execute arbitrary code. The issue, which was discovered by Google Project Zero's Ned Williamson and Xinru Chi of Pangu Lab, has been tracked as CVE-2023-23514. It's funny how Pangu went from jail breaking iOS to reporting vulnerabilities that could have been exploited for the same. The zero-day vulnerability was patched by improving the memory management of the OS. Apple has credited The Citizen Lab at The University of Toronto’s Munk School for assisting them with fixing the security loopholes.
