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 17.7 and iPadOS 17.7, iOS 18 and iPadOS 18, macOS Sequoia 15, macOS Sonoma 14.7, macOS Ventura 13.7, tvOS 18, visionOS 2, watchOS 11. Processing an image may lead to a denial-of-service.

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

This is an out-of-bounds access vulnerability in image processing functionality affecting multiple Apple operating systems (iOS, iPadOS, macOS, tvOS, visionOS, watchOS). The vulnerability occurs when processing a specially crafted image file, likely due to insufficient bounds checking in the image parsing code. Successful exploitation leads to denial-of-service via application or system crash.

MitigationApply the vendor-supplied security updates: iOS 17.7 and iPadOS 17.7, iOS 18 and iPadOS 18, macOS Sequoia 15, macOS Sonoma 14.7, macOS Ventura 13.7, tvOS 18, visionOS 2, and watchOS 11. Prioritize patching devices that process untrusted image content.

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 iOS version on iPhone
    Open Settings > General > About and note the version number under 'Version'
    Affected if Version is lower than 17.7 (for example, 17.6.1 or earlier)
  2. Check iPadOS version on iPad
    Open Settings > General > About and note the version number under 'Version'
    Affected if Version is lower than 17.7 (for example, 17.6.1 or earlier)
  3. Check macOS version on Mac
    Click Apple menu > About This Mac, or run 'sw_vers -productVersion' in Terminal
    Affected if Version is 13.x before 13.7, or 14.x before 14.7 (for example, 13.6 or 14.6)
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version
    Affected if Version is lower than 18.0 (for example, 17.6 or earlier)
  5. Check visionOS version on Vision Pro
    Open Settings > General > About and note the version number
    Affected if Version is lower than 2.0 (for example, 1.x)
  6. Check watchOS version on Apple Watch
    On paired iPhone, open Watch app > My Watch > General > About, or on Watch go to Settings > General > About
    Affected if Version is lower than 11.0 (for example, 10.x)

You are affected if any of your Apple devices run an OS version lower than the fixed releases: iOS/iPadOS 17.7, macOS 13.7/14.7, tvOS 18, visionOS 2, or watchOS 11.

Interim mitigation

Apply the vendor-supplied security updates: iOS 17.7 and iPadOS 17.7, iOS 18 and iPadOS 18, macOS Sequoia 15, macOS Sonoma 14.7, macOS Ventura 13.7, tvOS 18, visionOS 2, and watchOS 11. Prioritize patching devices that process untrusted image content.

Recommended fix High confidence

iOS 17.7 / iOS 18 / iPadOS 17.7 / iPadOS 18 / macOS Ventura 13.7 / macOS Sonoma 14.7 / macOS Sequoia 15 / tvOS 18 / visionOS 2 / watchOS 11 (depending on device and current OS family)

  1. Identify the current iOS, iPadOS, macOS, tvOS, visionOS, or watchOS version on the affected device
  2. Determine which OS version family the device is running (e.g., iOS 17, iOS 18, macOS Ventura 13.x, macOS Sonoma 14.x, macOS Sequoia 15.x, tvOS 18.x, visionOS 2.x, watchOS 11.x)
  3. Back up the device data before upgrading
  4. Upgrade to the fixed version corresponding to the OS family: iOS 17.x devices to 17.7, iOS 18.x devices to 18, iPadOS 17.x to 17.7, iPadOS 18.x to 18, macOS Ventura 13.x to 13.7, macOS Sonoma 14.x to 14.7, macOS Sequoia 15.x to 15, tvOS 18.x to 18, visionOS 2.x to 2, watchOS 11.x to 11
  5. Verify the upgrade was successful by checking the OS version in Settings > General > About
Caveat Standard upgrade risks apply - ensure backups exist and review app compatibility before upgrading
