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. An attacker may be able to elevate 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 · moderate confidence

This is a local privilege escalation vulnerability in Apple's operating systems. The fix with 'improved checks' indicates a missing validation or authorization check that allowed a local attacker to elevate privileges. The vulnerability affects multiple Apple platforms including iOS, iPadOS, and macOS across several version ranges.

MitigationApply the available security updates: iOS 16.7.8 and iOS 17.5+, iPadOS 16.7.8 and iPadOS 17.5+, macOS Monterey 12.7.5, macOS Ventura 13.6.7, and macOS Sonoma 14.5. Prioritize updating devices that handle sensitive data or have direct user access.

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. Identify the operating system type
    On iOS/iPadOS, go to Settings > General > About. On macOS, click the Apple menu and select About This Mac or run `sw_vers` in Terminal.
    Affected if The device runs iOS, iPadOS, or macOS within the affected version ranges below.
  2. Check iOS or iPadOS version
    On the device, go to Settings > General > About > Version. Note the exact version number shown.
    Affected if The version is less than 16.7.8, OR greater than or equal to 17.0 but less than 17.5.
  3. Check macOS version
    Click Apple menu > About This Mac, or run `sw_vers` in Terminal. Note the version shown (for example, 12.7.4, 13.6.6, or 14.4).
    Affected if The version is 12.0 to 12.7.4 (less than 12.7.5), OR 13.0 to 13.6.6 (less than 13.6.7), OR 14.0 to 14.4 (less than 14.5).
  4. Confirm affected status
    Cross-reference your identified OS type and version against the affected ranges: iOS/iPadOS < 16.7.8 or >= 17.0 to < 17.5; macOS 12.0 to < 12.7.5, 13.0 to < 13.6.7, or 14.0 to < 14.5.
    Affected if The installed version falls within any of these ranges, meaning the missing validation fix is not present and the system is potentially vulnerable to local privilege escalation.

If the device runs iOS or iPadOS below 16.7.8 or between 17.0 and 17.4, or macOS between 12.0 and 12.7.4, 13.0 and 13.6.6, or 14.0 and 14.4, then the environment is affected by this CVE.

Interim mitigation

Apply the available security updates: iOS 16.7.8 and iOS 17.5+, iPadOS 16.7.8 and iPadOS 17.5+, macOS Monterey 12.7.5, macOS Ventura 13.6.7, and macOS Sonoma 14.5. Prioritize updating devices that handle sensitive data or have direct user access.

Recommended fix High confidence

iOS 16.7.8, iOS 17.5, iPadOS 16.7.8, iPadOS 17.5, macOS 12.7.5, macOS 13.6.7, or macOS 14.5 (depending on current OS version)

  1. Identify the current iOS/iPadOS version on the device by going to Settings > General > About
  2. For devices running iOS 16.x: Update to iOS 16.7.8 or later via Settings > General > Software Update
  3. For devices running iOS 17.x: Update to iOS 17.5 or later via Settings > General > Software Update
  4. For iPad devices running iPadOS 16.x: Update to iPadOS 16.7.8 or later via Settings > General > Software Update
  5. For iPad devices running iPadOS 17.x: Update to iPadOS 17.5 or later via Settings > General > Software Update
  6. On Mac devices, check the macOS version via Apple menu > About This Mac
  7. For macOS Monterey (12.x): Update to macOS 12.7.5 via System Settings > Software Update
  8. For macOS Ventura (13.x): Update to macOS 13.6.7 via System Settings > Software Update
Caveat Standard iOS/macOS security updates have minimal risk; some older applications may experience compatibility issues
