If you’re an iPhone user, you’ve probably noticed a new update popping up in your Settings app. Apple just released iOS 18.6.2 on August 20, 2025, and while it might not come with flashy new features, it’s one you shouldn’t skip.
What’s New in iOS 18.6.2?
Unlike major point releases that introduce new emojis or UI tweaks, iOS 18.6.2 is laser-focused on security. According to Apple’s official notes, this update patches a critical flaw in the ImageIO framework. This component handles image processing on your device, and the vulnerability (tracked as CVE-2025-43300) could allow attackers to execute arbitrary code by tricking you into opening a maliciously crafted image. In simpler terms, hackers could potentially slip spyware onto your iPhone through something as innocent as a booby-trapped photo in a message or email.
This isn’t just theoretical—reports indicate that this exploit is actively being used in targeted attacks, possibly linked to spyware campaigns. Apple has classified it as a zero-day vulnerability, meaning it was discovered after bad actors started exploiting it. The patch ensures that processing such images no longer poses a risk, keeping your data and device safe.
Beyond the security fix, there aren’t any notable bug fixes or performance improvements mentioned in the release notes. This comes hot on the heels of iOS 18.6.1, which re-enabled blood oxygen monitoring on the latest Apple Watches and included its own set of security updates. If you’re already on 18.6.1, this is a quick follow-up to plug that remaining hole.
Apple also rolled out companion updates: iPadOS 18.6.2 for compatible iPads and macOS Sequoia 15.6.1 for Macs, addressing the same ImageIO issue across the ecosystem.
Device Compatibility
iOS 18.6.2 is available for a wide range of devices, starting from the iPhone XS and later models. That includes:
• iPhone XS, XS Max, XR
• iPhone 11 series
• iPhone 12 series
• iPhone 13 series
• iPhone 14 series
• iPhone 15 series
• iPhone 16 series (if you’re on the latest)
For iPads, it’s iPad Pro (2018 and later), iPad Air (2019 and later), iPad (2019 and later), and iPad mini (2019 and later). If your device is eligible for iOS 18, you can grab this update.
Why You Should Update Right Now
Security experts are urging everyone to install iOS 18.6.2 immediately. With the vulnerability already in use by attackers, delaying could leave your iPhone exposed to spyware or other malicious activities. These kinds of exploits are often used in sophisticated attacks, like those targeting journalists, activists, or high-profile individuals, but they can spread wider if not patched quickly.
Plus, updating is straightforward and usually takes just a few minutes. No need to back up your device manually (though it’s always a good habit), as iOS handles that automatically during the process.
How to Install iOS 18.6.2
Updating is easy:
1. Open the Settings app on your iPhone.
2. Tap General.
3. Select Software Update.
4. If iOS 18.6.2 appears, tap Update Now (or Download and Install if it’s not ready yet).
5. Enter your passcode and let it do its thing—your iPhone will restart once complete.
Make sure you’re connected to Wi-Fi and have at least 50% battery (or plug it in) to avoid interruptions.
Final Thoughts
iOS 18.6.2 might not be the most exciting update, but it’s a reminder of how Apple prioritizes user security with timely patches. As we edge closer to iOS 19 (rumored for later this year), these minor releases keep our devices running smoothly and safely in the meantime.
