Today, Apple released several new operating system updates to the public: iOS 15.3, iPadOS 15.3, macOS Monterey 12.2, watchOS 8.4, tvOS 15.3, and HomePod Software 15.3.

The update notes for these releases are some of the leanest I've seen. iOS, iPadOS, and macOS simply state that the update "includes bug fixes and security updates" and is "recommended for all users."

iOS and iPadOS 15.3 do not add any new user-facing features. Rather, they fix several key security issues. The most notable is a zeroday vulnerability that was being exploited in the wild. Tracked as CVE-2022-22587, the threat stems from a memory corruption bug in the IOMobileFrameBuffer. Hackers who successfully exploit the bug can execute malicious code with kernel privileges on vulnerable devices. The vulnerability also resides in macOS Monterey.
