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 issue was discovered in certain Apple products. macOS before 10.13.3 is affected. The issue involves the "Kernel" component. It allows attackers to execute arbitrary code in a privileged context via a crafted app.

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 · moderate confidence

A kernel-level vulnerability in macOS prior to 10.13.3 allows a specially crafted application to execute arbitrary code with elevated privileges, potentially giving attackers full control of the affected system.

MitigationUpdate macOS to version 10.13.3 or later to apply the kernel security patch.

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 installed macOS version
    Open Terminal and run 'sw_vers -productVersion' to display the currently installed macOS version
    Affected if The version shown is less than 10.13.3 (for example, 10.13.2, 10.13.1, 10.12.x, or earlier)
  2. Confirm kernel version as secondary check
    Run 'uname -r' in Terminal to display the kernel release version
    Affected if The kernel version corresponds to a macOS release earlier than 10.13.3

Your system is affected if it runs any macOS version lower than 10.13.3, as the kernel vulnerability exists in those releases regardless of configuration.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
