Apple has just released iOS 18.6.2 – and unlike some of its more routine patches, this one fixes a single, serious security flaw that’s prevalent across most of its devices, not just the iPhone. There are no flashy new features to explore here, but we’d still recommended you grab the update ASAP.
Critical security fix
According to Apple, the problem lies in the ImageIO framework. In plain English, that means a malicious image file could cause memory corruption on your device – and Apple says it’s already aware of the vulnerability being exploited in “an extremely sophisticated attack against specific targeted individuals.”
When Apple rushes to patch a single flaw across multiple operating systems at the same time, it signals that the risk is significant. The company isn’t sharing all the details, as that could help hackers, but the takeaway is simple: update as soon as possible.
Recent updates recapped
This comes hot on the heels of iOS 18.6.1, released earlier this month. That update quietly introduced a new way of handling Blood Oxygen readings on Apple Watch Series 9, Series 10, and Apple Watch Ultra 2 in the US, shifting the calculation to iPhone and displaying the results in the Health app.
Before that, iOS 18.6 itself rolled out in late July with 24 separate bug fixes, security patches, and a Photos fix for sharing memory movies. EU users also saw changes to the way alternative app stores are handled – with Apple replacing alarming warnings with a lengthy onboarding process.
So if you haven’t updated for a few weeks, you’ve missed quite a lot. Time to catch up!
How to update to iOS 18.6.2
Even if you have Automatic Updates switched on, it’s usually quicker to do it yourself. Open Settings > General > Software Update and follow the prompts to download and install.
The same advice applies across the board – iPadOS 18.6.2, macOS, and even older versions of macOS like Ventura have received this same patch. In other words, no matter which Apple device you’re using, now is the time to update.
