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 information disclosure issue was addressed with improved private data redaction for log entries. This issue is fixed in iOS 17.6 and iPadOS 17.6, macOS Sonoma 14.6, tvOS 17.6, visionOS 1.3, watchOS 10.6. A local attacker may be able to determine kernel memory layout.

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 local information disclosure vulnerability in Apple's log redaction mechanism allowed unredacted kernel memory layout information to be written to log entries. A local attacker with code execution or log access could potentially use this kernel memory layout information to defeat ASLR protections in kernel exploits.

MitigationApply the vendor-supplied patches for the affected Apple operating systems (iOS 17.6+, iPadOS 17.6+, macOS Sonoma 14.6+, tvOS 17.6+, visionOS 1.3+, watchOS 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
    Go to Settings > General > About > Software Version on the device
    Affected if The version is earlier than 17.6
  2. Check macOS version
    Click the Apple menu and select About This Mac
    Affected if The version is earlier than 14.6 (Sonoma)
  3. Check tvOS version
    Go to Settings > General > About > Version on the Apple TV
    Affected if The version is earlier than 17.6
  4. Check watchOS version
    Open the Watch app on paired iPhone, go to General > About
    Affected if The version is earlier than 10.6
  5. Check visionOS version
    Go to Settings > General > About on the Vision Pro device
    Affected if The version is earlier than 1.3
  6. Inspect system logs for unredacted kernel addresses
    Review system log files (such as via Console app on macOS or logd on iOS) for entries that may contain kernel memory addresses or memory layout information that should have been redacted
    Affected if Logs contain readable kernel memory addresses or heap/layout metadata that appears unredacted

The environment is affected if the installed Apple OS version is below the patched release (17.6 for iOS/iPadOS/tvOS, 14.6 for macOS, 1.3 for visionOS, 10.6 for watchOS) AND system logs contain unredacted kernel memory layout information.

Interim mitigation

Apply the vendor-supplied patches for the affected Apple operating systems (iOS 17.6+, iPadOS 17.6+, macOS Sonoma 14.6+, tvOS 17.6+, visionOS 1.3+, watchOS 10.6+).

Recommended fix High confidence

iOS 17.6 / iPadOS 17.6 / macOS Sonoma 14.6 / tvOS 17.6 / visionOS 1.3 / watchOS 10.6

  1. Identify the affected Apple device (iPhone, iPad, Mac, Apple TV, Apple Vision Pro, or Apple Watch)
  2. Check the current installed OS version in Settings > General > About (iOS/iPadOS/watchOS/visionOS) or System Settings > General > About (macOS)
  3. Back up the device data using iCloud or Finder/iTunes as a precaution
  4. For iPhone/iPad: Go to Settings > General > Software Update and install iOS 17.6/iPadOS 17.6
  5. For Mac: Go to System Settings > General > Software Update and install macOS Sonoma 14.6
  6. For Apple TV: Go to Settings > System > Software Updates and install tvOS 17.6
  7. For Apple Vision Pro: Go to Settings > General > Software Update and install visionOS 1.3
  8. For Apple Watch: On the iPhone, open the Watch app, go to My Watch > General > Software Update and install watchOS 10.6
Caveat Standard minor OS updates typically have minimal breaking changes; however, some apps or configurations may not be compatible with the newOS version
