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.

dbcve analysis · moderate confidence

A buffer overflow vulnerability in macOS kernel allows a local application to potentially cause system termination (DoS) or write to arbitrary kernel memory, leading to privilege escalation. The issue was addressed in macOS Ventura 13.3 with improved memory handling bounds checks.

MitigationApply macOS Ventura 13.3 or later security update. This is a kernel-level vulnerability that requires operating system patching; organizations should ensure endpoint detection and vulnerability management tools are scanning for this 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
    Run `sw_vers -productVersion` in Terminal to retrieve the exact macOS version number
    Affected if Version displays as 13.0, 13.1, 13.2, or any 13.2.x release (e.g., 13.2.1)
  2. Confirm version is within affected range
    Compare the version from step 1 against the vulnerable range: 13.0 <= version < 13.3
    Affected if The version falls between 13.0 and 13.2.x inclusive, meaning the kernel still contains the unpatched vulnerability
  3. Verify patch status via system_profiler
    Run `system_profiler SPSoftwareDataType` and look for the macOS version and build number in the output
    Affected if Build number corresponds to an unpatched Ventura release prior to the 13.3 security update

If the system runs macOS Ventura 13.0 through 13.2.x, it is vulnerable to this kernel buffer overflow and requires the 13.3 or later security update.
