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 your 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
