Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

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.

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. Check macOS version on Mac computers
    Open System Preferences > About or run 'sw_vers' in Terminal. Look for the macOS version number (e.g., 12.3, 12.4)
    Affected if macOS version is 12.0.0, 12.1, 12.2, or 12.3 (any version >= 12.0.0 but < 12.4)
  2. Check iOS version on iPhone devices
    Go to Settings > General > About on the iPhone. Look for the iOS version number
    Affected if iOS version is any version lower than 15.5 (e.g., 15.4, 15.3, 15.2, etc.)
  3. Check iPadOS version on iPad devices
    Go to Settings > General > About on the iPad. Look for the iPadOS version number
    Affected if iPadOS version is any version lower than 15.5 (e.g., 15.4, 15.3, 15.2, etc.)
  4. Check watchOS version on Apple Watch
    Open the Watch app on paired iPhone, go to My Watch > General > About. Or on Apple Watch go to Settings > General > About
    Affected if watchOS version is any version lower than 8.6 (e.g., 8.5, 8.4, 8.3, etc.)
  5. Check tvOS version on Apple TV
    Go to Settings > General > About on Apple TV. Look for the tvOS version number
    Affected if tvOS version is any version lower than 15.5 (e.g., 15.4, 15.3, etc.)
  6. Check iTunes version on Windows
    Open iTunes, go to Help > About iTunes. Or right-click the iTunes icon, select Properties, and view the version under the Details tab
    Affected if iTunes version is any version lower than 12.12.4

A user is affected if any of their Apple devices (Mac, iPhone, iPad, Apple Watch, Apple TV) or Windows iTunes installation runs a version lower than the fixed releases (macOS 12.4, iOS/iPadOS 15.5, watchOS 8.6, tvOS 15.5, iTunes 12.12.4)
