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
A logic 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, visionOS 2. Network traffic may leak outside a VPN tunnel.

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 logic flaw in Apple's VPN implementation allows network traffic to bypass the encrypted VPN tunnel, potentially exposing sensitive communications to eavesdropping or interception. The vulnerability stems from insufficient checks in the VPN tunnel handling code, causing traffic to be routed outside the protected tunnel.

MitigationApply the vendor-supplied patches: iOS 17.7 and later, iOS 18 and later, iPadOS 17.7 and later, iPadOS 18 and later, macOS Ventura 13.7 and later, macOS Sonoma 14.7 and later, macOS Sequoia 15 and later, or visionOS 2 and later.

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. Determine the installed macOS version
    Go to Apple menu > About This Mac. Note the version number shown (e.g., 14.5, 13.6).
    Affected if The version is less than 13.7, or greater than or equal to 14.0 but less than 14.7.
  2. Determine the installed iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About. Note the iOS version number shown (e.g., 17.6).
    Affected if The version is less than 17.7.
  3. Determine the installed visionOS version
    Go to Settings > General > About on Apple Vision Pro. Note the version number shown.
    Affected if The version is less than 2.0.
  4. Check if a VPN profile is configured
    On macOS, go to System Settings > Network > VPN. On iOS/iPadOS, go to Settings > VPN. Look for any VPN configuration profiles listed.
    Affected if A VPN configuration exists on the device.
  5. Verify if VPN is currently connected
    Check the VPN status in the menu bar (macOS) or status indicator in Settings > VPN (iOS/iPadOS). Note whether the VPN shows as Connected.
    Affected if The VPN is actively connected while the device runs an affected OS version.

The device is affected if the installed OS version falls within the affected ranges (macOS < 13.7 or 14.0 <= version < 14.7; iOS/iPadOS < 17.7; visionOS < 2.0) AND a VPN configuration is present or active.

Recommended fix High confidence

macOS Ventura 13.7, macOS Sonoma 14.7, macOS Sequoia 15, iOS 17.7, iPadOS 17.7, iOS 18, iPadOS 18, visionOS 2.0

  1. Identify your current operating system version on the device (Settings > General > About on iOS/iPadOS/visionOS, System Settings > General > About on macOS)
  2. For macOS Ventura 13.x users: Update to macOS Ventura 13.7 via System Settings > Software Update
  3. For macOS Sonoma 14.x users: Update to macOS Sonoma 14.7 via System Settings > Software Update
  4. For macOS Sequoia 15.x users: Update to macOS Sequoia 15 via System Settings > Software Update
  5. For iPhone/iPad running iOS/iPadOS 17.x: Update to iOS 17.7 or iPadOS 17.7 via Settings > General > Software Update
  6. For iPhone/iPad running iOS/iPadOS 18.x: Update to iOS 18 or iPadOS 18 via Settings > General > Software Update
  7. For Apple Vision Pro users: Update to visionOS 2.0 via Settings > General > Software Update
  8. After updating, verify the VPN connection functions correctly and traffic remains within the tunnel
Caveat Standard Apple point releases typically include security fixes without major breaking changes; however, some third-party VPN clients may require updates for full compatibility
