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
The issue was addressed with improved authentication. This issue is fixed in macOS Sequoia 15.6. A local attacker may be able to elevate their 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

A local authentication weakness in macOS Sequoia allows an unprivileged local attacker to elevate their privileges to higher permissions. The vulnerability stems from insufficient authentication controls that were strengthened in the macOS 15.6 update.

MitigationApply macOS Sequoia 15.6 or later to remediate the authentication vulnerability; for enterprise fleets, deploy via MDM or patch management infrastructure.

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
    Open Terminal and run: sw_vers -productVersion
    Affected if The displayed version is below 15.6 (e.g., 15.5, 15.4, etc.)
  2. Confirm macOS Sequoia lineage
    Run: sw_vers -productName to verify the system is macOS rather than older Apple operating systems
    Affected if ProductName displays anything other than macOS and the version is below 15.6
  3. Verify build number (optional)
    Run: sw_vers -buildVersion to obtain the specific build, which can help confirm the exact patch level within the 15.x series
    Affected if Build number corresponds to a pre-15.6 release

The system is affected if it is running any version of macOS Sequoia prior to version 15.6.
