Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

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 the Apple product and OS version
    On the device, go to Settings > General > About (iOS/iPadOS/watchOS/tvOS/visionOS) or Apple menu > About This Mac (macOS) to find the version number and build number
    Affected if The detected version falls within any of the affected ranges listed for the product
  2. Confirm iOS version for iPhone
    Check iOS version: Settings > General > About > Software Version. Compare against affected ranges: < 16.7.6 OR >= 17.0 AND < 17.4
    Affected if iOS version is 16.7.5 or earlier, or between 17.0 and 17.3.x inclusive
  3. Confirm iPadOS version for iPad
    Check iPadOS version: Settings > General > About > Software Version. Compare against affected ranges: < 16.7.6 OR >= 17.0 AND < 17.4
    Affected if iPadOS version is 16.7.5 or earlier, or between 17.0 and 17.3.x inclusive
  4. Confirm macOS version
    Check macOS version: Apple menu > About This Mac. Compare against affected ranges: >= 12.0 AND < 12.7.4, OR >= 13.0 AND < 13.6.5, OR >= 14.0 AND < 14.4
    Affected if macOS version is 12.7.3 or earlier, 13.6.4 or earlier, or 14.3.x or earlier
  5. Confirm tvOS version for Apple TV
    Check tvOS version: Settings > General > About > Version. Compare against affected range: < 17.4
    Affected if tvOS version is 17.3.x or earlier
  6. Confirm visionOS or watchOS version
    Check visionOS: Settings > General > About. Check watchOS: Settings > General > About > watchOS Version. Compare against affected ranges: visionOS < 1.1, watchOS < 10.4
    Affected if visionOS is 1.0.x or earlier, or watchOS is 10.3.x or earlier

The environment is affected if the installed Apple operating system version matches any of the vulnerable ranges specified for that product, as this kernel vulnerability can be triggered by a malicious application running on the device.
