Apple has released security updates for older versions of macOS and iOS, including macOS Sonoma 14.8.4, macOS Sequoia 15.7.4, and iOS 18.7.5. These updates address multiple vulnerabilities in shared system components such as CoreAudio, CoreMedia, CFNetwork, the kernel, Sandbox, Wi-Fi, and ImageIO, which could potentially lead to memory corruption, denial-of-service, arbitrary file write, and other security issues.
Why it matters
Apple's decision to provide security updates for older operating system versions, even as they have moved on to newer releases, demonstrates the company's commitment to supporting its user base and ensuring the security of its devices, regardless of the software version. This is particularly important for users who may be unable to upgrade to the latest OS due to hardware limitations or enterprise certification requirements.
