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 Disk Images component in Apple iOS before 9 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors.

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 privilege escalation and memory corruption vulnerability in the Disk Images component of Apple iOS versions prior to 9. The vulnerability allows a local attacker to potentially gain elevated privileges or cause a denial of service through memory corruption via unspecified vectors.

MitigationUpgrade affected iOS devices to version 9 or later to address this vulnerability.

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 the installed iOS version
    Go to Settings > General > About on the iOS device and note the Version number. Alternatively, connect the device to a computer with iTunes or Finder and check the device summary page for the iOS version.
    Affected if The version is 8.4.1 or lower, or any version prior to 9.0 (e.g., 8.4, 8.3, 8.2, etc.)
  2. Check the installed Mac OS X version
    Click the Apple menu in the top-left corner, select About This Mac, and note the version number displayed under the macOS name.
    Affected if The version is 10.10.5 or lower (e.g., 10.10.4, 10.10.3, etc.)
  3. Check the installed watchOS version
    Open the Watch app on the paired iPhone, go to General > About, and note the watchOS version.
    Affected if The version is exactly 1.0 (the only affected watchOS version)
  4. Verify Disk Images functionality is accessible
    On iOS, check if the device supports mounting or interacting with disk images. On macOS, verify if Disk Utility or diskimgutil tools are available and the system can process disk images.
    Affected if The Disk Images component (diskimgutil, Disk Utility, or related services) is present and operational on the device

The environment is affected if the installed OS version falls within the affected ranges (iOS <= 8.4.1, Mac OS X <= 10.10.5, watchOS 1.0) and the Disk Images component is accessible on the device.
