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 out-of-bounds access issue was addressed with improved bounds checking. This issue is fixed in iOS 18.6 and iPadOS 18.6, iPadOS 17.7.9, macOS Sequoia 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7, tvOS 18.6, visionOS 2.6, watchOS 11.6. Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory.

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 memory corruption vulnerability in Apple operating systems allows out-of-bounds memory access when processing specially crafted media files. The flaw exists in the media parsing component and can be triggered by a user opening a malicious media file, potentially causing application crashes or heap memory corruption.

MitigationApply the vendor-supplied security updates: iOS 18.6/iPadOS 18.6/17.7.9, macOS Sequoia 15.6/Sonoma 14.7.7/Ventura 13.7.7, tvOS 18.6, visionOS 2.6, or watchOS 11.6 depending on the affected device.

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. Identify the device type and operating system
    Determine whether the device is an iPhone, iPad, Mac, Apple TV, Apple Watch, or Apple Vision Pro. Note that this vulnerability affects multiple Apple platform OSes.
    Affected if The device runs any of the affected Apple operating systems.
  2. Check the installed iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About to view the version number. Compare against the affected ranges: < 17.7.9, or >= 18.0 and < 18.6.
    Affected if The installed iOS/iPadOS version falls within the affected ranges.
  3. Check the installed macOS version
    On Mac, go to Apple menu > About This Mac to view the version. Compare against affected ranges: >= 13.0 and < 13.7.7, >= 14.0 and < 14.7.7, or >= 15.0 and < 15.6.
    Affected if The installed macOS version falls within the affected ranges.
  4. Check tvOS, watchOS, or visionOS version
    On Apple TV, go to Settings > General > About. On Apple Watch, use the Watch app on iPhone > General > About. On Apple Vision Pro, go to Settings > General > About. Compare each against their respective affected ranges.
    Affected if The installed tvOS version is < 18.6, watchOS is < 11.6, or visionOS is < 2.6.
  5. Assess media file processing exposure
    Determine whether the device regularly processes media files from untrusted sources, such as opening attachments, streaming content from unknown sources, or using third-party media applications.
    Affected if The device processes media files from untrusted sources and runs an affected OS version.

A user is affected if their device runs an Apple OS version within the specified vulnerable ranges AND they process media files from potentially untrusted sources.
