Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify your Apple device type
    Determine whether the device is an iPhone, iPad, Mac, Apple TV, or Apple Watch. On iOS devices: check Settings > General > About > Model Name. On Mac: check Apple menu > About This Mac. On Apple TV: check Settings > General > About > Model. On Apple Watch: check Settings > General > About.
    Affected if Device is any Apple product running iOS, iPadOS, macOS, watchOS, or tvOS
  2. Check the installed OS version
    On iPhone/iPad: Settings > General > About > Version. On Mac: Apple menu > About This Mac > macOS version. On Apple TV: Settings > General > About > tvOS Version. On Apple Watch: Settings > General > About > watchOS Version.
    Affected if Unable to retrieve the OS version from the device
  3. Compare version against affected ranges
    Match your installed version to the affected version list for your device type: iOS < 15.3, iPadOS < 15.3, macOS 10.15.7 or earlier, macOS 11.0-11.6.2, macOS 12.0-12.1, watchOS < 8.4, tvOS < 15.3
    Affected if Installed version falls within any of these vulnerable ranges

Your environment is affected if the device runs an unpatched iOS, iPadOS, macOS, watchOS, or tvOS version prior to the fixed releases (iOS 15.3+, iPadOS 15.3+, watchOS 8.4+, tvOS 15.3+, macOS 11.6.3+, macOS 12.2+, or Security Update 2022-001 for Catalina).
