Apple has rolled out iOS 14.4.1 alongside iPadOS 14.4.1, macOS Big Sur 11.2.3 and watchOS 7.3.2, and every owner of a supported device should install it right away. Unlike a typical feature release, this update is focused entirely on security, patching a serious memory corruption flaw that surfaced after the earlier iOS 14.4 and iPadOS 14.4 builds shipped about a month prior. Apple is urging all users to update without delay.
Why iOS 14.4.1 Is a Critical Security Update
Apple normally bundles new features with each release, but this time the company prioritized protection. The update closes a memory corruption vulnerability that, if left unpatched, could let an attacker exploit your device. According to Apple, a hacker could use a maliciously crafted web link to trigger the bug and execute harmful code. Because the flaw spans Apple devices broadly, the same fix was issued across iPhone, iPad, Mac and Apple Watch at the same time.
iOS 14.4.1 Supported Devices and Compatibility
The iOS 14.4.1 update is available for all iPhone 6s models and later. On the tablet side, iPadOS 14.4.1 covers the iPad mini 4, iPad Air 2 and all newer iPad models. If your device runs iOS or iPadOS 14, this security patch is available to you.

How to Download and Install the Update
Installing is straightforward. Open the Settings app on your iPhone or iPad, tap General, then choose Software Update and follow the prompts. Before you begin, make sure your device has at least 50 percent battery so the installation completes safely. Mac and Apple Watch owners should apply their respective updates the same way.
Should You Update Right Away?
Yes. Because the patched vulnerability could be exploited simply by opening a malicious web link, Apple has asked every user to install the update as soon as possible. There is no downside to updating, and it keeps your device protected against the known threat.
