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 integer overflow was addressed through improved input validation. This issue is fixed in macOS Sequoia 15.3, macOS Sonoma 14.7.3, macOS Ventura 13.7.3. An app may be able to elevate 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 · moderate confidence

Integer overflow vulnerability in macOS that allows a malicious application to potentially elevate privileges to root or kernel level. The flaw exists due to insufficient input validation on integer operations, which can cause unexpected behavior when values exceed expected bounds.

MitigationApply the vendor-supplied patches by updating to macOS Sequoia 15.3, macOS Sonoma 14.7.3, or macOS Ventura 13.7.3 as appropriate for the affected system.

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. Determine installed macOS version
    Run 'sw_vers -productVersion' in Terminal or open About This Mac (Apple menu > About This Mac) to see the exact version number
    Affected if The version is less than 13.7.3, OR between 14.0 and 14.7.2 inclusive, OR between 15.0 and 15.2 inclusive

A system is affected if it runs any macOS version older than 13.7.3, 14.7.3, or 15.3 respectively.

Generated from the published advisory. Verify against your own configuration.
