Apple released updates for iOS/iPadOS, macOS, and Safari on Monday. There have been no updates for other Apple operating systems (visionOS, watchOS, tvOS). Usually, Apple updates all products at the same time.
Most of the vulnerabilities affect the web browser (WebKit, libxslt, WebRTC, and Web Extension). Only four of the vulnerabilities are not directly related to web content: Three Kernel issues and one vulnerability in the IOGPUFamily.
None of the vulnerabilities is labeled as "exploited".
