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 unspecified integrated graphics driver routine in the Intel Graphics Driver subsystem in Apple OS X before 10.9.5 does not properly validate calls, which allows attackers to execute arbitrary code in a privileged context via a crafted application, a different vulnerability than CVE-2014-4395, CVE-2014-4396, CVE-2014-4397, CVE-2014-4398, CVE-2014-4399, CVE-2014-4400, CVE-2014-4401, and CVE-2014-4416.

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 · high confidence

A privilege escalation vulnerability in the Intel Graphics Driver subsystem for OS X versions prior to 10.9.5 allows attackers to execute arbitrary code in a privileged context due to improper validation of calls in an integrated graphics driver routine. The attacker must trick the user into running a crafted malicious application.

MitigationUpdate Mac systems running OS X versions before 10.9.5 to OS X 10.9.5 or later to patch the vulnerable Intel Graphics Driver component. Verify graphics functionality after the update.

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
    Click Apple menu > About This Mac, or run 'sw_vers' in Terminal. Look for the version number displayed.
    Affected if Version shows 10.8.5, 10.9, 10.9.1, 10.9.2, 10.9.3, or 10.9.4 (any version before 10.9.5)
  2. Confirm Intel Graphics Driver presence
    Check System Report > Graphics/Displays section in System Information, or look for Intel graphics kexts in /System/Library/Extensions/ (search for IntelGraphics*.kext)
    Affected if Intel integrated graphics driver is present and in use on the system
  3. Verify graphics driver version
    Run 'kextstat | grep -i intel' in Terminal to list loaded Intel kernel extensions, or check the Intel Graphics Driver version in System Information > Graphics
    Affected if Unable to determine driver version or driver is from an older bundle predating the 10.9.5 update

A user is affected if their Mac runs OS X 10.9.4 or earlier (including 10.8.5 or any 10.9.x version before 10.9.5) and uses an Intel integrated graphics driver.
