Apple releases security update for iPhone 6s, iPhone 7 and other older devices: Full list
Apple has released a new set of security updates for several older iPhones and iPads, including devices like the iPhone 6s and iPhone 7. The update aims to fix serious security vulnerabilities discovered in older versions of iOS and iPadOS.
The updates include iOS 16.7.15, iOS 15.8.7, iPadOS 16.7.15, and iPadOS 15.8.7, and are specifically designed for devices that no longer support the latest versions of iOS.
Apple released these patches after security researchers discovered a dangerous exploit toolkit called the Coruna exploit kit, which could potentially allow attackers to compromise devices running outdated operating systems.
What is the Coruna exploit kit?
Security researchers from Google and cybersecurity firm iVerify recently identified the Coruna exploit kit, a sophisticated cyberattack toolkit that chains together 23 separate vulnerabilities.
This exploit targets weaknesses in two critical components:
- WebKit, the browser engine used by Safari
- The system kernel, which controls core device operations
In many cases, attackers only need to trick users into clicking a malicious link or visiting a compromised website. Once triggered, the exploit can allow hackers to gain deeper access to the device.
Apple confirmed that the newly released updates patch these vulnerabilities and block the exploit chain.
List of iPhones receiving the update
The security patch is available for several older iPhone models that are still widely used:
- iPhone 6s (2015)
- iPhone 7 (2016)
- iPhone 8 (2017)
- iPhone X (2017)
- iPhone SE (1st generation) (2016)
iPads covered by the update
Apple has also rolled out the patch for older iPad models, including:
- iPad mini 4
- iPad Pro (1st generation)
Although these devices no longer receive major feature updates, Apple continues to release security fixes to keep them protected from cyber threats.
Updates for newer Apple devices
Alongside patches for older hardware, Apple also released iOS 26.3.1 and iPadOS 26.3.1 for newer devices.
These updates mainly focus on:
- Bug fixes
- Performance improvements
- Better stability
- Compatibility with accessories such as the Apple Studio Display
While they do not introduce major new features, they improve overall system reliability.
Why updating your device is important
Security experts strongly recommend installing the update as soon as possible. Devices running outdated software are more vulnerable to cyberattacks, data theft, and malware infections.
Even older devices can remain secure if users regularly install the latest patches released by Apple.
How to update your iPhone or iPad
To install the latest update on your device:
- Open Settings
- Tap General
- Select Software Update
