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

This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, tvOS 17.6, visionOS 1.3, watchOS 10.6. 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.

dbcve analysis · high confidence

An out-of-bounds read vulnerability in Apple's file processing components allows a maliciously crafted file to trigger unexpected app termination. The issue was addressed through improved input validation, preventing the read operation from accessing memory outside allocated bounds.

MitigationApply the available OS updates (iOS 16.7.9/17.6, iPadOS 16.7.9/17.6, macOS 12.7.6/13.6.8/14.6, tvOS 17.6, visionOS 1.3, watchOS 10.6) to all affected devices. Since this is an OS-level vulnerability with no custom code fix possible, patch deployment is the sole remediation pathway.

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 device and operating system
    Determine whether the device is an iPhone (iOS), iPad (iPadOS), Mac (macOS), Apple TV (tvOS), Apple Vision (visionOS), or Apple Watch (watchOS). This determines which version ranges apply.
    Affected if The device runs any of the affected Apple operating systems (iOS, iPadOS, macOS, tvOS, visionOS, or watchOS).
  2. Check the installed iOS or iPadOS version
    On iPhone or iPad: Open Settings > General > About and note the version number. Compare it against the affected ranges: < 16.7.9, or >= 17.0 and < 17.6.
    Affected if The version is 16.7.8 or earlier, or any 17.0.x through 17.5.x version.
  3. Check the installed macOS version
    On Mac: Open System Settings > About (or System Preferences > About on older macOS) and note the version number. Compare against the affected ranges: < 12.7.6, >= 13.0 and < 13.6.8, or >= 14.0 and < 14.6.
    Affected if The version is 12.7.5 or earlier, any 13.0.x through 13.6.7 version, or any 14.0.x through 14.5 version.
  4. Check the installed tvOS, visionOS, or watchOS version
    On Apple TV: Settings > General > About > tvOS version. On Apple Vision: Settings > General > About > visionOS version. On Apple Watch: Settings > General > About > watchOS version. Compare against affected ranges: tvOS < 17.6, visionOS < 1.3, watchOS < 10.6.
    Affected if The tvOS version is 17.5 or earlier, visionOS is 1.2 or earlier, or watchOS is 10.5 or earlier.

A device is affected if it runs any version of iOS, iPadOS, macOS, tvOS, visionOS, or watchOS that falls within the specific vulnerable ranges listed for that operating system.
