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.

NVD · unedited
An out-of-bounds read issue was addressed with improved input validation. This issue is fixed in iOS 17.7 and iPadOS 17.7, iOS 18 and iPadOS 18, macOS Sequoia 15, macOS Sonoma 14.7, tvOS 18, visionOS 2, watchOS 11. Processing a maliciously crafted file may lead to unexpected app termination.

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 iOS version
    Go to Settings > General > About on iPhone or iPad. Note the Version number (e.g., 17.6.1).
    Affected if Version is below 17.7 (e.g., 17.6, 17.5, etc.)
  2. Check iPadOS version
    Go to Settings > General > About on iPad. Note the Version number.
    Affected if Version is below 17.7
  3. Check macOS version
    Click Apple menu > About This Mac. Note the version number (e.g., 14.6, 14.5).
    Affected if Version is below 14.7 (e.g., 14.6, 14.5, 13.x)
  4. Check tvOS version
    Go to Settings > General > About TV > Version on Apple TV.
    Affected if Version is 18.0 or earlier (including 17.x)
  5. Check visionOS version
    Go to Settings > General > About on Apple Vision Pro.
    Affected if Version is below 2.0 (e.g., 1.x)
  6. Check watchOS version
    Open the Watch app on paired iPhone, go to My Watch > General > About. Or on Apple Watch, go to Settings > General > About.
    Affected if Version is below 11.0 (e.g., 10.x)

You are affected if any of your Apple devices (iPhone, iPad, Mac, Apple TV, Vision Pro, or Apple Watch) run an OS version lower than the fixed versions (iOS/iPadOS 17.7+, macOS 14.7+, tvOS 18+, visionOS 2+, watchOS 11+).
