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 write issue was addressed with improved input validation. This issue is fixed in iOS 16.2 and iPadOS 16.2, iOS 15.7.2 and iPadOS 15.7.2, tvOS 16.2, watchOS 9.2. Parsing a maliciously crafted video file may lead to kernel code execution.

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

CVE-2022-46694 is an out-of-bounds write vulnerability in Apple's video parsing framework. A maliciously crafted video file triggers improper input validation during parsing, causing memory corruption that can be escalated to kernel-level code execution. This affects iOS, iPadOS, tvOS, and watchOS devices running unpatched versions.

MitigationApply the vendor-supplied patches: iOS 16.2/iOS 15.7.2 and iPadOS 16.2/iPadOS 15.7.2 for mobile devices, tvOS 16.2 for Apple TV, and watchOS 9.2 for Apple Watch. Prioritize patching given the kernel code execution impact.

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 your Apple device type
    Determine whether the device is an iPhone, iPad, Apple TV, or Apple Watch. This dictates which OS version to check.
    Affected if Device is an iPhone, iPad, Apple TV, or Apple Watch running an affected OS version
  2. Check iOS version on iPhone
    Go to Settings > General > About on iPhone and note the version number displayed next to 'Software Version'.
    Affected if iOS version is below 15.7.2, or is 16.0, 16.1 (versions 16.0 through 16.1 are affected)
  3. Check iPadOS version on iPad
    Go to Settings > General > About on iPad and note the version number displayed next to 'Software Version'.
    Affected if iPadOS version is below 15.7.2, or is 16.0, 16.1 (versions 16.0 through 16.1 are affected)
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version on Apple TV to see the installed tvOS version.
    Affected if tvOS version is below 16.2 (all versions prior to 16.2 are affected)
  5. Check watchOS version on Apple Watch
    Open the Watch app on paired iPhone, go to My Watch > General > About, or on Apple Watch go to Settings > General > About to find the watchOS version.
    Affected if watchOS version is below 9.2

The device is affected if it is an iPhone, iPad, Apple TV, or Apple Watch running an unpatched OS version within the affected ranges, meaning iOS/iPadOS below 15.7.2 or between 16.0 and 16.1, tvOS below 16.2, or watchOS below 9.2.

Upgrade available Upgrade to 9.2 / 15.7.2 / 16.2 or later
Fixed in 9.215.7.216.2
Interim mitigation

Apply the vendor-supplied patches: iOS 16.2/iOS 15.7.2 and iPadOS 16.2/iPadOS 15.7.2 for mobile devices, tvOS 16.2 for Apple TV, and watchOS 9.2 for Apple Watch. Prioritize patching given the kernel code execution impact.

Recommended fix High confidence

iOS 15.7.2 / iPadOS 15.7.2 / iOS 16.2+ / iPadOS 16.2+ / tvOS 16.2 / watchOS 9.2 (minimum fixed versions per platform)

  1. Identify the affected device (iPhone, iPad, Apple TV, or Apple Watch)
  2. Check the current installed iOS/iPadOS/tvOS/watchOS version in Settings > General > About
  3. For iPhone/iPad: If running iOS/iPadOS 15.x (< 15.7.2), upgrade to iOS/iPadOS 15.7.2 or later
  4. For iPhone/iPad: If running iOS/iPadOS 16.x (< 16.2), upgrade to iOS/iPadOS 16.2 or later
  5. For Apple TV: Upgrade to tvOS 16.2 or later
  6. For Apple Watch: Upgrade to watchOS 9.2 or later
  7. Perform the upgrade via Settings > General > Software Update (iPhone/iPad/Watch) or Settings > Apple TV > Software Updates (Apple TV)
  8. After upgrade, verify the device is running a fixed version
Caveat Standard Apple OS update considerations apply - review release notes for any app compatibility issues before upgrading
