It is Apple’s policy not to disclose security threats or breaches until an investigation has taken place. When an update is made available, you know that Apple is taking it seriously and you should follow its advice. The latest patch plugs a few holes in the iOS kernel and WebKit, but it’s not all security-focused. It also brings with it several improvements for your device.

What can these security flaws do to your Apple device?

iOS 14.3 has a security flawThe flaw affects the iOS/ iPadOS Kernel and WebKitIt can give a hacker complete access to your deviceIt can also cause malicious apps to infiltrate your dataYou should update to iOS 14.4 immediately

An anonymous researcher alerted Apple to a flaw in iOS 14.3, where an attacker could theoretically take control of a device. The company didn’t go into much detail surrounding the possible intrusion, simply saying that a malicious application may be able to elevate privileges. That means an app loaded with malware may be able to access functions and operations on your device that it normally wouldn’t have access to. This could include things like your email address, telephone number or even Apple Pay details. This could also trigger remote access, and the hacker would have total control of your phone. Apple didn’t independently confirm whether the exploit has been used but said that it “is aware of a report that this issue may have been actively exploited.” For WebKit, Apple details that “a remote attacker may be able to cause arbitrary code execution.” Again, it would allow a hacker to trigger things in the device that it isn’t supposed to. In addition to iOS 14.4 and iPadOS 14.4, updates were also released for watchOS 7.3 and tvOS 14.4.

What else is in the patch?

Several improvements have been bundled into the iOS 14.4 update — the majority fixing issues with the camera.
