Apple Issues Critical Security Updates for Older iPhones and iPads to Counter Coruna Exploit

Apple Releases Critical Security Updates for Older iOS and iPadOS Devices

In a significant move to bolster the security of its legacy devices, Apple has rolled out iOS 16.7.15, iPadOS 16.7.15, iOS 15.8.7, and iPadOS 15.8.7. These updates are specifically designed for older iPhones and iPads that are not compatible with the latest iOS versions. Users can access these updates by navigating to Settings > General > Software Update on their devices. For those with automatic updates enabled, the new software will be installed automatically in the coming days.

Apple’s release notes emphasize that these updates include important security fixes. Notably, they address vulnerabilities associated with the Coruna exploit, a sophisticated attack that leverages multiple vulnerabilities to target iPhones running older iOS versions. The Coruna exploit was disclosed last week by Google and iVerify, highlighting the urgency of these updates.

The Coruna exploit involves chaining multiple vulnerabilities, allowing attackers to gain unauthorized access to devices. By releasing these updates, Apple aims to protect users of older devices from potential security breaches. The company has committed to providing security updates for iPhones for at least five years after launch, but often extends support beyond that period. Earlier this year, the iPhone 5s received a new software update 13 years after its initial release. ([macrumors.com](https://www.macrumors.com/2026/03/11/apple-ios-16-7-15-release/?utm_source=openai))
