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
IBM AIX 7.2, 7.3, VIOS 3.1, and 4.1 could allow a non-privileged local user to exploit a vulnerability in the AIX perfstat kernel extension to cause a denial of service.

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 vulnerability in the AIX perfstat kernel extension allows a non-privileged local user to cause a denial of service. The vulnerability is locally exploitable by an authenticated user without elevated privileges, leading to a system crash or service disruption.

MitigationApply the IBM AIX security patch for the perfstat kernel extension vulnerability. Review IBM's security bulletin for the specific patch level required for AIX 7.2, 7.3, VIOS 3.1, and VIOS 4.1.

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 operating system
    Run 'oslevel -s' on the system to determine if it is IBM AIX or VIOS
    Affected if The OS is not AIX or VIOS, then this CVE does not apply
  2. Check the AIX version
    Run 'oslevel -s' and examine the output. For AIX, the version should start with 7200 (AIX 7.2) or 7300 (AIX 7.3)
    Affected if The AIX version is 7200 or 7300, the system falls within the affected version range
  3. Check the VIOS version
    Run 'ioslevel' to determine the VIOS version
    Affected if The VIOS version is 3.1.0 or 4.1.0, the system falls within the affected version range
  4. Verify perfstat kernel extension availability
    Run 'perfstat' command or check with 'lsdev -c perfstat' to see if the perfstat device is configured
    Affected if The perfstat kernel extension is present and accessible to local users

The environment is affected if it runs IBM AIX 7.2 or 7.3, or VIOS 3.1 or 4.1, and the perfstat kernel extension is available to local users.
