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

Updates address two main security flaws. A vulnerability, CVE-2022-22675, exists on all three platforms and allows malicious actors to execute arbitrary code with kernel privileges in an application—essentially allowing hackers to run whatever code they want on your device. The other flaw, CVE-2022-22674, is specific to macOS and occurs 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, which makes these updates particularly critical.

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

  • The battery may drain faster than expected after updating to iOS 15.4/iPadOS 15.4.
  • Braille devices may become unresponsive when navigating through text or displaying an alert.
  • Made for iPhone/iPad hearing aids may lose connection with some third-party apps.

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