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
An issue was addressed with improved validation of environment variables. 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, watchOS 10.5. An app may be able to access sensitive user 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

This vulnerability involves improper validation of environment variables in Apple operating systems, which could allow a malicious application to read sensitive user data stored in or accessible through environment variables. Environment variables often contain paths, user information, and other potentially sensitive configuration data that were not being properly sandboxed or validated.

MitigationApply the vendor-supplied patches by updating to iOS 16.7.8/17.5, iPadOS 16.7.8/17.5, macOS Monterey 12.7.5/Ventura 13.6.7/Sonoma 14.5, tvOS 17.5, or watchOS 10.5 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 version on iPhone
    Go to Settings > General > About and note the version number (e.g., 17.4)
    Affected if Version is less than 16.7.8, or greater than or equal to 17.0 but less than 17.5
  2. Check iPadOS version on iPad
    Go to Settings > General > About and note the version number
    Affected if Version is less than 16.7.8, or greater than or equal to 17.0 but less than 17.5
  3. Check macOS version on Mac
    Click the Apple menu > About This Mac and note the version number (e.g., 14.4)
    Affected if Version is less than 12.7.5, or greater than or equal to 13.0 but less than 13.6.7, or greater than or equal to 14.0 but less than 14.5
  4. Check tvOS version on Apple TV
    Go to Settings > General > About and note the version number
    Affected if Version is less than 17.5
  5. Check watchOS version on Apple Watch
    Open the Watch app on paired iPhone, go to General > About and note the version number
    Affected if Version is less than 10.5

You are affected if your device runs any version lower than the patched release for your specific Apple operating system (iOS 16.7.8/17.5, macOS 12.7.5/13.6.7/14.5, tvOS 17.5, or watchOS 10.5).

Interim mitigation

Apply the vendor-supplied patches by updating to iOS 16.7.8/17.5, iPadOS 16.7.8/17.5, macOS Monterey 12.7.5/Ventura 13.6.7/Sonoma 14.5, tvOS 17.5, or watchOS 10.5 as appropriate for each affected device.

Recommended fix High confidence

Upgrade to iOS 16.7.8, iOS 17.5, iPadOS 16.7.8, iPadOS 17.5, macOS 12.7.5, macOS 13.6.7, macOS 14.5, tvOS 17.5, or watchOS 10.5 depending on current OS and device type

  1. Identify the current installed iOS, iPadOS, macOS, tvOS, or watchOS version on the device
  2. For iPhone or iPad: Go to Settings > General > Software Update to check for and install iOS 16.7.8 or iOS 17.5 (and corresponding iPadOS versions)
  3. For Mac: Go to System Settings > General > Software Update to check for and install macOS 12.7.5 (Monterey), 13.6.7 (Ventura), or 14.5 (Sonoma)
  4. For Apple TV: Go to Settings > System > Software Updates to check for and install tvOS 17.5
  5. For Apple Watch: On the iPhone, open the Watch app, go to My Watch > General > Software Update to check for and install watchOS 10.5
  6. After updating, verify the update was successful by checking the installed OS version in Settings/About
Caveat Standard Apple OS updates may have minimal compatibility impacts; backup device before updating
