Apple has Released iOS 15.7.5, macOS 11.7.6, And macOS 12.6.5, All of Which Include Improvements to Their Respective Operating Systems’ Security

Apple has released new versions of iOS (15.7.5), macOS Big Sur (11.7.6), and macOS Monterey (12.6.5) today. These updates bring security enhancements to older Macs, iPads, and iPhones that cannot run the latest iOS (16), iPadOS (16), and macOS Ventura versions.

By navigating to Settings > General > Software Update on compatible iPhones and iPads, users can get the iOS 15.7.5 update wirelessly over the air.

The upgrades for macOS Big Sur and macOS Monterey can be downloaded onto a Mac by navigating to the System Preferences menu, clicking on the General option, and then clicking on Software Update.

On Friday of last week, Apple released iOS 16.4.1 and macOS Sierra 13.3.1, which included updates for vulnerabilities being actively exploited. The software updates are available today address the same concerns on earlier devices. Apple is aware of two distinct vulnerabilities exploited in the wild.

Because of a vulnerability in IOSurfaceAccelerator, an application may be able to execute arbitrary code while maintaining kernel privileges. Apple fixed the out-of-bounds write problem by improving the input validation in their software. Because of a security flaw in WebKit, maliciously created online content could execute code on a user’s device. Apple resolved this issue by improving the way it managed its memory.

It is believed that the Threat Analysis Group at Google and the Security Lab at Amnesty International were the ones who discovered both vulnerabilities and informed Apple about them.
