PSA: Make Sure to Update Older Devices to iOS 15.7.4 to Fix Actively Exploited Vulnerability

Alongside the iOS 16.4 and iPadOS 16.4 updates, Apple today released iOS 15.7.4 and iPadOS 15.7.4, which is available to those using older devices that are not able to be upgraded to the latest software. It is important for those with an older iPhone or iPad to download the software as soon as possible, because it includes important security fixes.

According to Apple's release notes for the security update, it addresses a long list of vulnerabilities, including a WebKit vulnerability that was known to be actively exploited. From Apple's security support document:

Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.

Note that those running iOS 16 and iPadOS 16 do not need to worry about this exploit as it was previously fixed in iOS 16.3.1. The update also fixes other WebKit vulnerabilities that were not actively exploited, plus it fixes security issues with Calendar, Camera, Find My, and more.

iOS 15.7.4 and iPadOS 15.7.4 are available for all iPhone 6s models, all iPhone 7 models, the first-generation iPhone SE, the iPad Air 2, the fourth-generation iPad mini, and the seventh-generation iPod touch.

Now if only our 15.x devices would show us the 15.7.4 update as an option other than only 16.4. ☹️

It's astonishing Apple continues to support old devices as far back as the iPhone 6s. The iPhone 6s was released in 2015. 🫨

P.S. I couldn't resist. I used a new stuttering emoji. Can you guys see it? The new emojis are getting to us today. Yes, I'm part of the problem.

Is it possible to update to 15.7.4 if your device (in my case 13 mini) is capable of running iOS 16? Any way to achieve that?
Not that I can see.

I have an iPhone on iOS 15.7.3 that cannot run iOS 16 so Apple made iOS 15.7.4 update available for it. I have another device on iOS 15.7.1 that can run iOS 16, but there's no option to install iOS 15.7.4 (just like there wasn't an option to install iOS 15.7.2 or iOS 15.7.3), just iOS 16.4

Apple's software support for older hardware is one of the reasons I will continue to stick with Apple.

I can't see the new emoji. I guess MacRumors needs to update the site. 😢
