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
A double free issue was addressed with improved memory management. This issue is fixed in iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, macOS Ventura 13.7.6. An app may be able to cause unexpected system 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

A double-free vulnerability in memory management allows a malicious or compromised application to free the same memory pointer twice, leading to heap corruption and potential system termination. This issue was addressed with improved memory management in the affected Apple operating systems.

MitigationApply the available security updates: iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, or macOS Ventura 13.7.6 depending on the deployed platform.

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 operating system
    Determine whether the device runs iPadOS or macOS. On iPad, go to Settings > General > About to see iPadOS version. On Mac, click the Apple menu > About This Mac to see macOS version.
    Affected if Running iPadOS or macOS (this CVE does not affect other platforms)
  2. Check iPadOS version
    If the device is an iPad, note the iPadOS version from Settings > General > About. Compare it against the affected range: any version lower than 17.7.7 is vulnerable.
    Affected if iPadOS version is lower than 17.7.7
  3. Check macOS Ventura version
    If running macOS Ventura (13.x), note the exact version from About This Mac. Compare against the affected range: any version lower than 13.7.6 is vulnerable.
    Affected if macOS Ventura version is lower than 13.7.6
  4. Check macOS Sonoma version
    If running macOS Sonoma (14.x), note the exact version from About This Mac. Compare against the affected range: version 14.0 or higher but lower than 14.7.6 is vulnerable.
    Affected if macOS Sonoma version is 14.0 or higher but lower than 14.7.6
  5. Check macOS Sequoia version
    If running macOS Sequoia (15.x), note the exact version from About This Mac. Compare against the affected range: version 15.0 or higher but lower than 15.5 is vulnerable.
    Affected if macOS Sequoia version is 15.0 or higher but lower than 15.5

The environment is affected if the installed iPadOS version is below 17.7.7, or the installed macOS version (Ventura, Sonoma, or Sequoia) falls below the corresponding fixed version for that release.

Interim mitigation

Apply the available security updates: iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, or macOS Ventura 13.7.6 depending on the deployed platform.

Recommended fix High confidence

iPadOS 17.7.7, macOS Ventura 13.7.6, macOS Sonoma 14.7.6, or macOS Sequoia 15.5 depending on current OS version

  1. Identify the current iPadOS or macOS version on the affected device
  2. For macOS: Open System Settings > General > Software Update (or System Preferences > Software Update on older versions)
  3. For iPadOS: Open Settings > General > Software Update
  4. Check for available updates and install the appropriate version for your current OS: iPadOS 17.7.7, macOS Ventura 13.7.6, macOS Sonoma 14.7.6, or macOS Sequoia 15.5
  5. Restart the device if prompted to complete the installation
Caveat Standard Apple OS updates may include compatibility changes with older applications; major version jumps (e.g., Ventura to Sonoma) have higher change risk than point releases
