Apple’s latest iPhone software has just been released, almost a month after iOS 26.5.1, which was exclusively for iPhone 17 series handsets and iPhone Air. It has a focus on security, not new features. That’s not surprising, given we’re at the end of the iOS 26 cycle. Here’s what the update is all about and how to get it.
Which iPhones Can Run iOS 26.5.2?
This update is for all iPhones which can run iOS 26, specifically, all models from the iPhone 11 onwards. It means that unless you have one of the iPhone 17 or iPhone Air models, you’ll be coming to it from iOS 26.5, not iOS 26.5.1.
How To Download And Install iOS 26.5.2
The process is familiar by now, I’m sure: open the Settings app and choose General, followed by Software Update. Here you’ll find Download and Install, and it’ll be downloaded promptly. It’s a small update, around 700MB on my iPhone 17 Pro Max, which meant it downloaded and installed in less than 10 minutes.
iOS 26.5.2 — What’s In The Release
Apple’s release notes specify that the content is all security-related. Intriguingly, the company’s support document detailing the security content reveals that the security fixes have already been made available to beta users in the form of the iOS 26.6 betas.
Since iOS 26.6 is expected to land in the next week or two, it’s an indication that Apple regards the fixes important enough to be released now instead.
The biggest part of the release is more than a dozen elements relating to WebKit, the web browser engine. That’s around half of the total fixes in the update. There are also three fixes for the Kernel, the engine that underpins the operating system.
The vulnerabilities address issues such as apps causing system termination, malicious web content leading to crashes or other issues such as memory corruption or hijacking of clipboard data.
“None of the vulnerabilities are known to have been actively exploited, but now that Apple has published details about them, it is possible malicious entities could create exploits targeting users who have not yet updated,” MacRumors reported.
