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 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, macOS Tahoe 26.3, tvOS 26.3, visionOS 26.3, watchOS 26.3. 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 · moderate confidence

An out-of-bounds access vulnerability exists in Apple's media processing frameworks (likely in a media codec or parser). The vulnerability allows processing of a maliciously crafted media file to trigger memory corruption or application termination due to insufficient bounds checking during media parsing.

MitigationApply the Apple security updates for the relevant platform (iOS 18.7.5/26.3, iPadOS 18.7.5/26.3, macOS 15.7.4/14.8.4/26.3, tvOS 26.3, visionOS 26.3, or watchOS 26.3) to all affected devices. For custom applications using Apple's media frameworks, review media parsing code and implement proper bounds validation.

    Affected if The installed iPadOS version is less than 18.7.5, or is 26.0, 26.1, or 26.2
  3. Check macOS version on Macs
    Click the Apple menu > About This Mac and note the macOS version number
    Affected if The installed macOS version is less than 14.8.4, or is between 15.0 and 15.7.3 inclusive, or is 26.0, 26.1, or 26.2
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version on Apple TV
    Affected if The installed tvOS version is less than 26.3
  5. Check visionOS version on Vision Pro
