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 · uneditedAn out-of-bounds write issue was addressed with improved input validation. This issue is fixed in macOS Monterey 12.7.4, macOS Sonoma 14.4, macOS Ventura 13.6.5. 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 confidenceAn out-of-bounds write vulnerability in the macOS kernel that allows a malicious application to write data beyond allocated memory boundaries, potentially enabling arbitrary code execution with kernel-level privileges. The issue was addressed through improved input validation in the security updates.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed macOS versionOpen System Settings > General > About, or run `sw_vers` in Terminal, or run `system_profiler SPSoftwareDataType`Affected if The version shown falls within these ranges: 12.0 to 12.7.3, 13.0 to 13.6.4, or 14.0 to 14.3
You are affected if your macOS version is 12.x between 12.0 and 12.7.3, 13.x between 13.0 and 13.6.4, or 14.x between 14.0 and 14.3 (any version below the patched releases 12.7.4, 13.6.5, or 14.4).
