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
A vulnerability in GSKit affects IBM Spectrum Scale 4.1.1, 4.2.0, 4.2.1, 4.2.3, and 5.0.0 that could allow a local attacker to obtain control of the Spectrum Scale daemon and to access and modify files in the Spectrum Scale file system, and possibly to obtain administrator privileges on the node. IBM X-Force ID: 139240.

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 vulnerability in GSKit (IBM Global Security Kit) affects IBM Spectrum Scale versions 4.1.1 through 5.0.0. The flaw allows a local attacker to obtain control of the Spectrum Scale daemon, enabling access and modification of files in the Spectrum Scale file system, potentially leading to full administrator/root privileges on the affected node.

MitigationApply IBM's security patches for this GSKit vulnerability to affected Spectrum Scale installations, or upgrade to a patched version. This is a local privilege escalation issue requiring existing shell access, so prioritize patching systems with exposure to untrusted local users.

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 if IBM Spectrum Scale or GPFS is installed
    Run 'mmversion' or check for the presence of /usr/lpp/-spectrumscale (Spectrum Scale) or /usr/lpp/gpfs (GPFS) directories
    Affected if Neither Spectrum Scale nor GPFS is installed on the system
  2. Determine the installed Spectrum Scale version
    Execute 'mmversion -a' or check installed RPMs with 'rpm -qa | grep -i spectrumscale'
    Affected if The installed version falls within these ranges: 4.1.1.0 to 4.1.1.19, 4.2.0.0 to 4.2.0.4, 4.2.1.0 to 4.2.1.2, 4.2.2.0 to 4.2.2.3, 4.2.3.0 to 4.2.3.8, or 5.0.0.0 to 5.0.0.2
  3. Determine the installed GPFS version (if GPFS rather than Spectrum Scale)
    Execute 'mmversion -a' or check installed RPMs with 'rpm -qa | grep -i gpfs'
    Affected if The installed version falls within the range 4.1.0.0 to 4.1.0.8
  4. Verify the Spectrum Scale daemon is active
    Run 'mmgetstate -a' or check for running 'mmfsd' processes
    Affected if The Spectrum Scale daemon is running and the version is in any of the affected ranges listed above

The system is affected if it runs IBM Spectrum Scale version 4.1.1.0 through 5.0.0.2 or GPFS version 4.1.0.0 through 4.1.0.8, with the Spectrum Scale/GPFS daemon actively using the vulnerable GSKit component.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
