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 buffer overflow issue was addressed with improved memory handling. This issue is fixed in macOS Sonoma 14.6. An app may be able to execute arbitrary code with kernel privileges.

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

Buffer overflow vulnerability in macOS that allows a local application to escalate privileges to kernel level, enabling arbitrary code execution with the highest system privileges. Fixed in macOS Sonoma 14.6 via improved memory handling.

MitigationApply the Apple security update (macOS Sonoma 14.6 or later) to affected systems. This is a kernel-level patch requiring system restart.

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
    Run 'sw_vers -productVersion' in Terminal or go to Apple menu > About This Mac > System Report > Software > System Software Version
    Affected if Version is 14.0, 14.1, 14.2, 14.3, 14.4, or 14.5 (any version >= 14.0 but < 14.6)
  2. Confirm macOS name and build
    Run 'uname -a' to verify the kernel is Darwin-based, and check System Settings > General > About for the exact build number
    Affected if System is macOS Sonoma (14.x) but not yet on build 23F79 or later (14.6)

The system is affected if it runs macOS Sonoma version 14.0 through 14.5; it is NOT affected if running 14.6 or later.
