In a security advisory on its website, Apple said it was aware of two vulnerabilities that “may have been actively exploited on Intel-based Mac systems.” The bugs are considered “zero day” vulnerabilities because they were unknown to Apple at the time they were exploited.

The previously unknown " zero-day " flaws led Apple to issue patches for macOS, iOS, and iPadOS. Details are thin, but both bugs involve a Mac, iPhone, or iPad processing "maliciously crafted web content" to trigger the operating system to execute rogue computer code.

Apple warns Mac users about two critical zero-day vulnerabilities actively exploited by hackers. Urgent software updates are available for Mac, iPhone, and iPad to prevent malware attacks and data theft.
