Apple has recently released an update for older devices (iOS 15.7.4) with a number security patches. Now, it is rolling out another update (iOS 15.7.5 & iPadOS 15.7.5) iPhone and iPad devices. These updates address two vulnerabilities that may have been actively exploited.
The official release notes don’t mention any new features beyond the security enhancements. Apple simply says that iOS 15.7.5 provides important security fixes and is recommended for all users.
Updating your iPhone to iOS 15.7.5 is simple: Open the Settings app and choose General, then Software Update. The update is available for the following devices:
iPhone 6s (all models), iPhone 7 (all models), iPhone SE (1st generation), iPad Air 2, iPad mini (4th generation), and iPod touch (7th generation)
The two security issues that may have been actively exploited are:
An app may be able to execute arbitrary code with kernel privileges. This has been addressed with improved input validation.
This problem is caused by maliciously crafted web content that may lead to arbitrary code execution and has been fixed through improved memory management.
Whilst security issues continue to be a menace (and probably always will be), it is refreshing to see Apple providing enhanced protection, through fixes, for customers who still use older phones.
