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
Array index error in IOAcceleratorFamily in Apple OS X before 10.9.4 allows attackers to execute arbitrary code via a crafted application.

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 flaw in IOAcceleratorFamily within Apple OS X versions prior to 10.9.4 involves an array index boundary error that can be triggered by a malicious application, potentially allowing arbitrary code execution with kernel privileges.

MitigationUpgrade to OS X 10.9.4 or later to address the vulnerability; apply subsequent security updates as they become available.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 OS X version
    Open Terminal and run: sw_vers -productVersion
    Affected if The version returned is 10.8.0 through 10.9.3 (any of these: 10.8.0, 10.8.1, 10.8.2, 10.8.3, 10.8.4, 10.8.5, 10.9, 10.9.1, 10.9.2, or 10.9.3, or any version lower than 10.9.4)

If the system is running OS X 10.9.3 or earlier (including all 10.8.x versions), the IOAcceleratorFamily kernel extension contains the array index boundary flaw and the system is affected.

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

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 10.9.3
Interim mitigation

Upgrade to OS X 10.9.4 or later to address the vulnerability; apply subsequent security updates as they become available.

Recommended fix High confidence

OS X 10.9.4 or later (10.9.5 recommended); for 10.8.x users, upgrade to 10.9.5 first then to a supported macOS version

  1. 1. Back up your Mac using Time Machine or another backup solution before upgrading
  2. 2. For Mac OS X 10.8.x users: Upgrade to OS X 10.9.5 (the final Mavericks release) first, then consider upgrading to a newer supported macOS version
  3. 3. For Mac OS X 10.9.x users (version 10.9.3 or earlier): Upgrade to OS X 10.9.4 or later
  4. 4. After upgrading, verify the system is running the patched version by checking About This Mac
Caveat Upgrading from OS X 10.8.x to 10.9.x may remove support for older applications; some system requirements may change
