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
This issue was addressed by removing the vulnerable code. This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, watchOS 10.6. An app may be able to access user-sensitive data.

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

A vulnerability in multiple Apple operating systems (iOS, iPadOS, macOS, watchOS) allowed a malicious or compromised application to access user-sensitive data. The issue was resolved by removing the vulnerable code path.

MitigationApply the vendor-supplied security updates: update iOS/iPadOS to 16.7.9 or 17.6, macOS to 12.7.6, 13.6.8, or 14.6, and watchOS to 10.6.

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
    On the device, go to Settings > General > About and note the version number displayed next to 'Version'
    Affected if The version is earlier than 16.7.9, or is 17.0 through 17.5.x (any version >= 17.0 but < 17.6)
  2. Check macOS version
    On the Mac, go to System Settings > About (or System Preferences > About on older macOS) and note the version number displayed
    Affected if The version is earlier than 12.7.6, or is 13.0 through 13.6.7, or is 14.0 through 14.5.x (any version >= 13.0 but < 13.6.8, or >= 14.0 but < 14.6)
  3. Check watchOS version
    On the Apple Watch, open the Settings app, go to General > About and note the version number displayed
    Affected if The version is earlier than 10.6 (any version < 10.6)
  4. Determine if untrusted applications can be installed
    Check if the device allows installation of apps from unknown sources (sideloading) or if a malicious app could be installed via MDM or other means
    Affected if The device permits installation of applications from sources other than the official App Store without strong vetting, increasing the risk that a malicious app could exploit this vulnerability

The environment is affected if any Apple device (iPhone, iPad, Mac, or Apple Watch) is running an OS version that falls within the affected ranges listed above.

Fixed in 10.612.7.613.6.8
Interim mitigation

Apply the vendor-supplied security updates: update iOS/iPadOS to 16.7.9 or 17.6, macOS to 12.7.6, 13.6.8, or 14.6, and watchOS to 10.6.

Recommended fix High confidence

iOS 16.7.9 or iOS 17.6; iPadOS 16.7.9 or iPadOS 17.6; macOS 12.7.6, 13.6.8, or 14.6; watchOS 10.6 depending on current OS

  1. Open Settings on the device
  2. Navigate to General > Software Update
  3. Download and install the available security update for your specific iOS/iPadOS/macOS/watchOS version
  4. For iOS 16.7.x users: install iOS 16.7.9
  5. For iOS 17.0-17.5 users: install iOS 17.6
  6. For iPadOS 16.7.x users: install iPadOS 16.7.9
  7. For iPadOS 17.0-17.5 users: install iPadOS 17.6
  8. For macOS Monterey 12.7.x users: install macOS Monterey 12.7.6
Caveat Apple security updates typically have no breaking changes; standard functionality is preserved
