Apple released new updates for iPhone (iOS 15.4.1), iPad (iPadOS 15.4.1), and Mac (macOS 12.3.1) yesterday, and according to the release notes, they fix some annoying bugs across platforms, including a battery drain issue many iPhone users experienced on iOS 15.4. However, Apple didn’t advertise the important security patches these updates also include, and you should install them as soon as possible.

The updates address two key security flaws. One vulnerability, CVE-2022-22675, exists among all three platforms and allows bad actors to execute arbitrary code with kernel privileges in an application — essentially letting hackers run whatever code they’d like to on your device. The other flaw, CVE-2022-22674, is macOS specific, occurring in Intel graphics drivers. This vulnerability allows an application to read you kernel memory.

Apple says it has reports that both vulnerabilities may have been used in the wild, making these updates especially critical.

That said, security patches aren’t the only reasons to update your devices. For iPhone and iPad, these updates include fixes to the following bugs:

  • Battery may drain more quickly than expected after updating to iOS 15.4/iPadOS 15.4.
  • Braille devices may become unresponsive while navigating text or displaying an alert.
  • Made for iPhone/iPad hearing devices may lose connection within some third-party apps.

Mac users can expect fixes to these two bugs, one of which will be especially welcome to gamers:

  • USB-C or Thunderbolt external display does not turn on when connected to Mac mini (2018) as a second display
  • Bluetooth devices, such as game controllers, may disconnect from your Mac after playing audio through some Beats headphones

How to update to iOS 15.4.1, iPadOS 15.4.1, and macOS 12.3.1

To update your iPhone or iPad to 15.4.1, head to Settings > General > Software Update. To update your Mac to macOS 12.3.1, go to System Preferences > Software Update. If the update is available on your device, you’ll see it here. Follow the on-screen instructions to download and install the software, to both protect yourself from these security flaws as well as fix these annoying bugs.
