Strong recommendation to install macOS 12.5.1 and iOS / iPadOS 15.6.1

Apple has released updates to the macOS 12.5.1, iOS 15.6.1 and iPadOS 15.6.1 operating systems for compatible Mac, iPhone, iPod and iPad models. Timely installation is recommended for all users, since all three system updates close two security gaps that have apparently already been actively exploited. In detail, these are errors in the kernel and in WebKit that are fixed with the patches. On the Mac, you can find the system update under System Preferences -> Software Update. On mobile devices, simply open Settings -> General -> Software update. Further information and links to the official Apple information can be found below.

In the support document published yesterday HT213413 on the subject, Apple states that the security update fixes problems with the kernel and WebKit. The information is currently only available in English and has not yet been translated into German. To give you an insight, I have transcribed the information freely:

  • Kernel: A program may be able to run arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited.
  • WebKit: Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.
