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 state management. This issue is fixed in tvOS 14.6, Security Update 2021-004 Mojave, iOS 14.6 and iPadOS 14.6, Security Update 2021-003 Catalina, macOS Big Sur 11.4, watchOS 7.5. A local user may be able to leak sensitive user information.

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 logic vulnerability in Apple's operating systems (macOS, iOS, iPadOS, watchOS, tvOS) allows a local authenticated user to leak sensitive user information due to improper state management. The attacker would need local access to the device to exploit this vulnerability.

MitigationApply the vendor-supplied security updates: tvOS 14.6, iOS 14.6/iPadOS 14.6, macOS Big Sur 11.4, Security Update 2021-003 for Catalina, Security Update 2021-004 for Mojave, and watchOS 7.5.

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 macOS version
    Run 'sw_vers -productVersion' in Terminal or go to Apple menu > About This Mac > macOS version
    Affected if The version is 10.14.x (10.14 to 10.14.6), 10.15.x (10.15 to 10.15.7), or 11.0 to 11.3.x (anything less than 11.4)
  2. Identify the iOS version
    Go to Settings > General > About on the iPhone or iPad, or use Apple Configurator 2 to check connected devices
    Affected if The version is less than 14.6 (for example, 14.5, 14.4, etc.)
  3. Identify the iPadOS version
    Go to Settings > General > About on the iPad, or use Apple Configurator 2 to check connected devices
    Affected if The version is less than 14.6
  4. Identify the tvOS version
    Go to Settings > General > About > Version on Apple TV, or use Xcode or Apple Configurator 2
    Affected if The version is less than 14.6 (for example, 14.5 or earlier)
  5. Identify the watchOS version
    Open the Watch app on iPhone, go to General > About, or check on the watch itself in Settings > General > About
    Affected if The version is less than 7.5

The system is affected if it runs any macOS version 10.14.x, 10.15.x, or 11.0-11.3.x; iOS/iPadOS version below 14.6; tvOS version below 14.6; or watchOS version below 7.5.

  1. Back up all important data before starting the update
  2. For iPhone/iPad: Go to Settings > General > Software Update and install iOS/iPadOS 14.6
  3. For Mac: Go to System Preferences > Software Update and install macOS Big Sur 11.4 or the appropriate Security Update (2021-004 for Mojave, 2021-003 for Catalina)
  4. For Apple Watch: On your iPhone, open the Watch app, go to My Watch > General > Software Update and install watchOS 7.5
  5. For Apple TV: Go to Settings > System > Software Updates and install tvOS 14.6
  6. Restart the device after the update completes
