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 operating system
    Determine whether the device runs iOS, iPadOS, macOS, tvOS, visionOS, or watchOS. This vulnerability affects all these Apple operating systems.
    Affected if The device runs any of these Apple operating systems.
  2. Check iOS or iPadOS version
    Open Settings > General > About and note the version number displayed (for example, 18.7.1 or 26.4).
    Affected if The installed version is less than 18.7.9, OR is 26.0 or higher but less than 26.5.
  3. Check macOS version
    Click the Apple menu > About This Mac. Note the version number (for example, 14.6.1, 15.5, or 26.4).
    Affected if The installed version is 14.0 or higher but less than 14.8.7, OR is 15.0 or higher but less than 15.7.7, OR is 26.0 or higher but less than 26.5.
  4. Check tvOS, visionOS, or watchOS version
    Open Settings > General > About on the Apple TV, Vision Pro, or Apple Watch. Note the version number.
    Affected if The installed version is lower than 26.5.

You are affected if your device runs any of the listed Apple operating systems and its current version falls within the specific vulnerable ranges shown for that product.
