Apple patches two actively exploited security flaws with iOS 16.5.1 and more

Coming with the release iOS 16.5.1, macOS 13.4.1, and more today, Apple has shipped two important fixes for security flaws. The updates arrive for devices on the latest public software and those on older versions of its software. Notably, Apple has heard the flaws have been actively exploited.

The main user-facing feature coming with iOS 16.5.1 is a fix for a bug with the Lightning to USB Camera Adapter.

However, for almost all of Apple’s devices including iPhone 6s and later, modern iPads and Macs, and even Apple Watches, there are two important security patches that come with the latest updates.

Two patches for exploited security flaws

The first flaw patch is for a vulnerability that allows the execution of arbitrary code with kernel privileges. And the second is a WebKit flaw fix that stops maliciously crafted web content from being able to execute arbitrary code.

Apple says it is aware of reports stating both flaws have been actively exploited, so make sure to update your devices as soon as possible.
