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
Intel Graphics Driver in Apple OS X before 10.12 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

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

Memory corruption vulnerability in the Intel Graphics Driver component in Apple OS X versions prior to 10.12. Attackers can exploit this by tricking a user into running a crafted malicious application, potentially achieving arbitrary code execution with elevated privileges or causing a denial of service through memory corruption.

MitigationUpgrade affected systems to macOS Sierra (10.12) or later, which includes the patched Intel Graphics Driver. Prioritize systems running OS X El Capitan (10.11) and earlier.

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 Version displays 10.11.6 or lower (10.11.0 through 10.11.6)
  2. Confirm OS X release name
    Run: sw_vers -productVersion and note the major.minor version (10.11.x indicates El Capitan)
    Affected if Version begins with 10.11 (any minor version) as these are all <= 10.11.6
  3. Identify Intel Graphics Driver presence
    Check for Intel graphics hardware by running: system_profiler SPDisplaysDataType | grep -i intel
    Affected if Intel integrated graphics hardware is present and the driver would be loaded on affected OS versions
  4. Verify graphics driver module
    Check if the Intel graphics kernel extension exists: ls /System/Library/Extensions/IOAcceleratorFamily2.kext (or similar Intel graphics kexts)
    Affected if Intel graphics kext files exist on the system, indicating the vulnerable driver component is present

A system is affected if it runs OS X version 10.11.6 or earlier and has Intel Graphics Driver loaded (typical on Macs with Intel integrated graphics).

Upgrade available Upgrade to a release after 10.11.6
Interim mitigation

Upgrade affected systems to macOS Sierra (10.12) or later, which includes the patched Intel Graphics Driver. Prioritize systems running OS X El Capitan (10.11) and earlier.
