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 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Monterey 12.7.5, macOS Sonoma 14.5, macOS Ventura 13.6.7, tvOS 17.5, visionOS 1.2. An app may be able to execute arbitrary code with kernel privileges.

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 a kernel-level privilege escalation vulnerability affecting multiple Apple operating systems (iOS, iPadOS, macOS, tvOS, visionOS). A malicious application could exploit insufficient checks to execute arbitrary code with kernel privileges, effectively gaining complete control over the device.

MitigationApply the vendor-supplied patches by updating to iOS 16.7.8/17.5+, iPadOS 16.7.8/17.5+, macOS 12.7.5/13.6.7/14.5, tvOS 17.5, or visionOS 1.2 as appropriate for each 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. Check iOS or iPadOS version
    Go to Settings > General > About on the device and note the version number shown next to 'Version'
    Affected if The version is below 16.7.8, OR between 17.0 and 17.4.x (any version >= 17.0 but < 17.5)
  2. Check macOS version
    Click the Apple menu > About This Mac and note the version number displayed (such as 13.5 or 14.4)
    Affected if The version is below 12.7.5, OR between 13.0 and 13.6.6 (any version >= 13.0 but < 13.6.7), OR between 14.0 and 14.4.x (any version >= 14.0 but < 14.5)
  3. Check tvOS version
    Go to Settings > General > About > Version on Apple TV
    Affected if The version is any version below 17.5 (that is, < 17.5)
  4. Check visionOS version
    Go to Settings > General > About on Apple Vision Pro
    Affected if The version is any version below 1.2 (that is, < 1.2)

If the operating system version on your device falls within any of the vulnerable ranges listed above, your device is affected by this kernel privilege escalation vulnerability.

  1. Identify the currently installed OS version on the affected device (iPhone, iPad, Mac, Apple TV, or Apple Vision Pro)
  2. Determine which product category and version range the device falls into from the affected versions list
  3. For iOS/iPadOS 16.x devices: upgrade to iOS/iPadOS 16.7.8 or later
  4. For iOS/iPadOS 17.0-17.4 devices: upgrade to iOS/iPadOS 17.5 or later
  5. For macOS Monterey (12.x) devices: upgrade to macOS 12.7.5 or later
  6. For macOS Ventura (13.x) devices: upgrade to macOS 13.6.7 or later
  7. For macOS Sonoma (14.x) devices: upgrade to macOS 14.5 or later
  8. For tvOS 17.x devices: upgrade to tvOS 17.5 or later
Caveat Standard OS update risks apply (possible app incompatibility with older apps not updated for newer iOS/macOS versions); backup devices before updating
