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 Ventura 13.3. An app may be able to cause unexpected system termination or write 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 macOS Ventura version
    Open Terminal and run: sw_vers -productVersion
    Affected if The version displayed is 13.0, 13.1, or 13.2 (any version from 13.0 up to but not including 13.3)
  2. Confirm kernel architecture is x86_64 or ARM64
    Run: uname -m to verify kernel architecture. This vulnerability affects both Intel and Apple Silicon Macs running vulnerable macOS versions.
    Affected if The system is running a vulnerable macOS Ventura version regardless of architecture

If sw_vers shows a version between 13.0 and 13.2 inclusive, the system is affected by this kernel buffer overflow vulnerability.
