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 was addressed with improved input validation. This issue is fixed in macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1. An app may be able to cause unexpected system termination or read kernel memory.

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 the installed macOS version
    Open Terminal and run: sw_vers -productVersion
    Affected if The version output is below 14.8.2, or is 15.0 through 15.7.1 (for example 15.0, 15.3, 15.6, 15.7.1)
  2. Confirm the major macOS release name
    Run: sw_vers -productVersion and note the first number (14 for Sonoma, 15 for Sequoia)
    Affected if Running Sonoma 14.x versions before 14.8.2, or Sequoia 15.0-15.7.1

The system is affected if it runs macOS Sonoma before 14.8.2 or macOS Sequoia between 15.0 and 15.7.1 inclusive.
