Apple releases iOS 15.7.5 with security fixes

Notable security patches were included in iOS 15.7.4, which was released by Apple to the general public last week.

Apple has recently rolled out iOS 15.7.5, an update for older iPhone and iPad models that addresses two significant security vulnerabilities that may have been actively exploited. In addition to the iPhone and iPadOS update, Apple has also released two new versions of macOS Big Sur, version 11.7.6 (20G1231), and macOS Monterey, version 12.6.5 (21G531).

The official release notes for iOS 15.7.5 primarily focus on the security enhancements included in the update. Apple notes that the new update "provides important security fixes and is recommended for all users." As such, the update doesn't come with any new features but instead aims to strengthen the security of older iPhone and iPad models.

Users of eligible devices can update their devices by heading to the Settings app, selecting General, and then choosing 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 build number for the update is 19H332.

The two vulnerabilities addressed in the iOS 15.7.5 update are related to IOSurfaceAccelerator and WebKit. The IOSurfaceAccelerator issue could allow an app to execute arbitrary code with kernel privileges. Apple is aware of reports that this issue may have already been actively exploited. The second vulnerability, related to WebKit, could potentially allow for arbitrary code execution when processing maliciously crafted web content. Again, Apple has noted that this issue may have already been actively exploited.

Finally, in addition to the iOS 15.7.5 update, Apple has also released new versions of macOS Big Sur and Monterey. These updates include similar security enhancements and fixes to further strengthen the security of Apple's operating systems.
