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
Multiple out-of-bounds write issues were addressed with improved bounds checking. This issue is fixed in macOS Monterey 12.5, watchOS 8.7, tvOS 15.6, iOS 15.6 and iPadOS 15.6. An app may be able to disclose kernel memory.

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

This is a kernel memory disclosure vulnerability in Apple's operating systems involving multiple out-of-bounds write issues. An attacker who tricks a user into installing a malicious app could exploit these memory corruption flaws to read sensitive kernel memory contents due to insufficient bounds checking in the affected code paths.

MitigationApply the vendor-supplied security updates: macOS Monterey 12.5, watchOS 8.7, tvOS 15.6, iOS 15.6, or iPadOS 15.6. Organizations should prioritize patching mobile devices and endpoints that support sideloaded applications.

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 your Apple device or Fedora system
    On Apple devices: Settings > General > About shows the product name and version. On macOS: System Preferences > About. On Fedora: run 'cat /etc/fedora-release' in Terminal.
    Affected if Any Apple product or Fedora system listed in the affected products.
  2. Check your iOS or iPadOS version
    Go to Settings > General > About > Version. Compare the shown version number to the affected range.
    Affected if Version is lower than 15.6 (e.g., 15.5, 15.4, etc.)
  3. Check your macOS version
    Click Apple menu > About This Mac. Compare the macOS version to the affected range.
    Affected if Version is 12.0 through 12.4 (any version from 12.0 up to but not including 12.5)
  4. Check your watchOS, tvOS version
    On Apple Watch: Open the Watch app on iPhone > General > About. On Apple TV: Go to Settings > General > About.
    Affected if watchOS is lower than 8.7, or tvOS is lower than 15.6
  5. Check your Fedora version
    Run 'cat /etc/fedora-release' or 'uname -r' in Terminal to get the kernel and OS version.
    Affected if Fedora version is exactly 35 or 36
  6. Determine if third-party app installation is possible
    On iOS/iPadOS: Check if App Store access is enabled. On macOS: Check if apps from unidentified developers can be installed (System Preferences > Security & Privacy > General).
    Affected if Running a vulnerable OS version AND the device allows installation of apps from third-party sources (App Store, sideloading, or unidentified developers)

You are affected if your Apple device runs any version lower than the fixed releases (iOS/iPadOS 15.6, macOS 12.5, watchOS 8.7, tvOS 15.6) or if you run Fedora 35 or 36, and you have the ability to install applications on the device.

Upgrade available Upgrade to 8.7 / 12.5 / 15.6 or later
Fixed in 8.712.515.6
Interim mitigation

Apply the vendor-supplied security updates: macOS Monterey 12.5, watchOS 8.7, tvOS 15.6, iOS 15.6, or iPadOS 15.6. Organizations should prioritize patching mobile devices and endpoints that support sideloaded applications.

Recommended fix High confidence

Apple devices: iOS 15.6+, iPadOS 15.6+, macOS 12.5+, watchOS 8.7+, tvOS 15.6+

  1. For iOS devices: Go to Settings > General > Software Update and upgrade to iOS 15.6 or later
  2. For iPadOS devices: Go to Settings > General > Software Update and upgrade to iPadOS 15.6 or later
  3. For macOS devices: Go to System Preferences > Software Update and upgrade to macOS Monterey 12.5 or later
  4. For Apple Watch: Go to Settings > General > Software Update on the watch and upgrade to watchOS 8.7 or later
  5. For Apple TV: Go to Settings > System > Software Updates and upgrade to tvOS 15.6 or later
  6. After upgrading, verify the version in Settings to confirm the security update is applied
Caveat Standard OS upgrade considerations apply - review app compatibility and back up data before upgrading
