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 out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed with improved input validation. This issue is fixed in macOS Monterey 12.3.1, Security Update 2022-004 Catalina, macOS Big Sur 11.6.6. A local user may be able to read 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 · moderate confidence

A local out-of-bounds read vulnerability in macOS allows an unprivileged local user to read kernel memory contents due to insufficient input validation. This information disclosure could potentially aid further privilege escalation attacks.

MitigationApply the vendor-supplied security updates: macOS Monterey 12.3.1, Security Update 2022-004 for Catalina, or macOS Big Sur 11.6.6 to all affected systems.

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 installed macOS version
    Run 'sw_vers -ProductVersion' in Terminal to retrieve the exact version number of macOS
    Affected if The version matches 10.15.7, or falls within 11.0 to 11.6.6, or 12.0.0 to 12.3.1
  2. Confirm full version string
    Run 'sw_vers -ProductVersion' and note both the major.minor.patch (e.g., 12.3) and the build number from 'sw_vers -BuildVersion'
    Affected if The build version corresponds to an unpatched release within the affected version ranges
  3. Verify patch status via system profiler
    Run 'system_profiler SPSoftwareDataType' and look for the Security Update or macOS version entry in the output
    Affected if No Security Update 2022-004 (for Catalina), no macOS 11.6.6 update, or no macOS Monterey 12.3.1 update is listed as installed

A system is affected if it runs macOS 10.15.7, any version from 11.0 through 11.6.5, or any version from 12.0.0 through 12.3.0 without the corresponding security patch installed.
