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 10.13.1 is affected. The issue involves the "Kernel" component. It allows attackers to bypass intended memory-read restrictions 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 vulnerability in the macOS Kernel (prior to 10.13.1) allows a crafted application to bypass intended memory-read restrictions, potentially exposing sensitive kernel memory contents to user-space processes.

MitigationUpgrade to macOS 10.13.1 or later to obtain the Apple-supplied kernel 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. Identify installed macOS version
    Open Terminal and run: sw_vers -productVersion
    Affected if The displayed version is 10.13.0 or lower (10.13, 10.12.x, etc.)
  2. Confirm kernel version (optional verification)
    Run: uname -r in Terminal to display the kernel version
    Affected if Kernel version corresponds to macOS 10.13.0 or earlier (kernel Darwin 17.x.x for 10.13.0, lower for earlier versions)
  3. Check for recent third-party applications
    Review Applications folder and recent downloads for untrusted or unsigned applications that could be the crafted exploit
    Affected if Any untrusted or recently downloaded application has been executed on the system

The system is affected if it runs macOS 10.13.0 or earlier, and a malicious application has been executed that targets this kernel memory-read vulnerability.
