According to Apple, macOS 12.5.1, iOS 15.6.1, and iPadOS 15.6.1 updates are mandatory security updates, and users should install them as soon as possible to address critical security vulnerabilities.
Apple releases security updates for macOS, iOS, and iPadOS to fix actively exploited vulnerabilities
The common aspect among these three updates is that they all address a range of security vulnerabilities. One of them is tagged and marked as CVE ID CVE-2022-32894, a kernel-level vulnerability that could allow unauthorized apps to 'execute arbitrary code with kernel privileges'.
Another security vulnerability is identified as CVE ID CVE-2022-32893, a WebKit vulnerability allowing arbitrary code execution through 'maliciously crafted web content.' Apple uses WebKit in its applications, notably the Safari browser, and even the Mail app uses WebViews to render and display content.
Security vulnerabilities exist in the fundamental code widely used by Apple, so previous macOS versions, such as macOS Catalina and Big Sur, could also be vulnerable to attacks. However, the company has not issued any patches for these older versions yet.
Release notes for the updates do not mention any other bug fixes or features. Users are advised to update and install macOS 12.5.1, iOS 15.6.1, and iPadOS 15.6.1 updates as soon as possible.
