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 issue was addressed with improved checks. 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 13.7.1, visionOS 2. Processing a maliciously crafted file may lead to heap corruption.

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 heap corruption vulnerability exists in multiple Apple operating systems when processing maliciously crafted files. The vulnerability stems from insufficient input validation during file parsing, allowing an attacker to corrupt heap memory by providing specially crafted file content.

MitigationApply the vendor-supplied patches for the affected Apple operating systems (iOS 17.7+, iPadOS 17.7+, macOS Sequoia 15+, macOS Sonoma 14.7+, macOS Ventura 13.7.1+, visionOS 2+). Until patched, avoid opening untrusted files from unknown sources.

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
    Go to Settings > General > About > Version and note the OS version number
    Affected if Version is less than 17.7 (e.g., 17.6.x or earlier)
  2. Check iPadOS version on iPad
    Go to Settings > General > About > Version and note the OS version number
    Affected if Version is less than 17.7 (e.g., 17.6.x or earlier)
  3. Check macOS version
    Click Apple menu > About This Mac and note the version number under macOS name
    Affected if Version is 13.7 or earlier, OR version is 14.0 through 14.6 (any 14.x before 14.7)
  4. Check visionOS version
    Go to Settings > General > About and note the version number
    Affected if Version is less than 2.0 (e.g., 1.x versions)

Your device is affected if the installed OS version falls within any of the vulnerable version ranges: iOS/iPadOS below 17.7, macOS below 13.7.1 or between 14.0 and 14.6, or visionOS below 2.0.

Interim mitigation

Apply the vendor-supplied patches for the affected Apple operating systems (iOS 17.7+, iPadOS 17.7+, macOS Sequoia 15+, macOS Sonoma 14.7+, macOS Ventura 13.7.1+, visionOS 2+). Until patched, avoid opening untrusted files from unknown sources.

Recommended fix High confidence

iOS 17.7/iOS 18 (iPhone), iPadOS 17.7/iPadOS 18 (iPad), macOS Ventura 13.7.1/macOS Sonoma 14.7/macOS Sequoia 15 (Mac), visionOS 2 (Apple Vision)

  1. Identify the current version of the affected Apple device (iPhone, iPad, Mac, or Apple Vision)
  2. For iPhone or iPad: Navigate to Settings > General > Software Update to check the current iOS/iPadOS version
  3. For Mac: Navigate to System Settings > General > Software Update to check the current macOS version
  4. For Apple Vision: Navigate to Settings > General > Software Update to check the current visionOS version
  5. Based on current version, upgrade to one of the fixed releases: iOS 17.7, iOS 18, iPadOS 17.7, iPadOS 18, macOS Ventura 13.7.1, macOS Sonoma 14.7, macOS Sequoia 15, or visionOS 2
  6. After upgrade, verify the device is running a fixed version to confirm remediation
Caveat Standard Apple OS upgrades may have compatibility impacts with older applications; review app compatibility before upgrading
