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
This issue was addressed with improved checks. This issue is fixed in iOS 15.6 and iPadOS 15.6, macOS Big Sur 11.6.8, watchOS 8.7, tvOS 15.6, macOS Monterey 12.5, Security Update 2022-005 Catalina. A remote user may be able to cause unexpected system termination or corrupt 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

A remote attacker can exploit a kernel-level memory corruption vulnerability in multiple Apple operating systems (iOS, iPadOS, macOS, watchOS, tvOS) to cause system termination or corrupt kernel memory. The issue was addressed with improved bounds/validation checks in the kernel.

MitigationApply the available security updates: iOS 15.6+, iPadOS 15.6+, macOS Big Sur 11.6.8+, macOS Monterey 12.5+, watchOS 8.7+, tvOS 15.6+, or Security Update 2022-005 for Catalina. Prioritize remote-facing devices and those with network exposure.

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 operating system
    Determine whether the device runs iOS, iPadOS, macOS, watchOS, or tvOS. On macOS, run 'sw_vers' or click Apple menu > About This Mac. On iOS/iPadOS, go to Settings > General > About. On watchOS, go to Settings > General > About. On tvOS, go to Settings > General > About.
    Affected if The device runs any of the affected Apple operating systems listed in the CVE.
  2. Check iOS or iPadOS version
    On iOS/iPadOS, go to Settings > General > About and note the version number (for example, 15.5 or 15.6). Compare against the affected range of versions less than 15.6.
    Affected if The installed iOS or iPadOS version is below 15.6 (for example, 15.5, 15.4, 15.3, etc.).
  3. Check macOS version
    On macOS, click Apple menu > About This Mac or run 'sw_vers' in Terminal. Note the version number (for example, 12.4, 11.6.7, 10.15.7). Compare against the affected ranges: < 10.15.7; 10.15.7; >= 11.0 and < 11.6.8; >= 12.0 and < 12.5.
    Affected if The installed macOS version is 10.15.7, or less than 10.15.7, or between 11.0 and 11.6.7 inclusive, or between 12.0 and 12.4 inclusive.
  4. Check watchOS version
    On Apple Watch, go to Settings > General > About and note the version number. Or pair with iPhone and check in the Watch app under General > About. Compare against the affected range of versions less than 8.7.
    Affected if The installed watchOS version is below 8.7 (for example, 8.6, 8.5, 8.4, etc.).
  5. Check tvOS version
    On Apple TV, go to Settings > General > About TV and note the version number. Compare against the affected range of versions less than 15.6.
    Affected if The installed tvOS version is below 15.6 (for example, 15.5, 15.4, etc.).

The environment is affected if the installed iOS, iPadOS, macOS, watchOS, or tvOS version matches any of the specific version ranges listed as vulnerable in the CVE.
