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
Dell PowerScale OneFS 8.2.x, 9.0.0.x - 9.4.0.x, contain an insufficient resource pool vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to 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 · moderate confidence

Dell PowerScale OneFS contains an insufficient resource pool vulnerability where the system fails to properly restrict or allocate resources (such as memory, connections, or handles) to handle incoming requests. A remote unauthenticated attacker can exploit this by exhausting available resources, causing the system to become unavailable to legitimate users.

MitigationApply the vendor-provided security update or patch for Dell PowerScale OneFS to address the resource pool vulnerability. If immediate patching is not possible, implement network-level access controls to limit exposure to untrusted networks.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 PowerScale OneFS version
    Run the command to display the OneFS version (e.g., isi version via CLI or check the web administration UI system information page)
    Affected if The installed version falls within these ranges: 9.1.0.0 through 9.1.0.25, 9.2.1.0 through 9.2.1.18, or 9.4.0.0 through 9.4.0.9 (any version >= 9.1.0.0 and < 9.1.0.26, >= 9.2.1.0 and < 9.2.1.19, or >= 9.4.0.0 and < 9.4.0.10)
  2. Verify available patches are applied
    Consult the OneFS patch management interface or release notes to confirm whether all available security updates have been installed
    Affected if The system is running an affected version and has not had the corresponding security patch applied

A system is affected if it runs PowerScale OneFS version 9.1.0.x before 9.1.0.26, 9.2.1.x before 9.2.1.19, or 9.4.0.x before 9.4.0.10 and is reachable by remote unauthenticated network attackers.

Fixed in 9.1.0.269.2.1.199.4.0.10
Interim mitigation

Apply the vendor-provided security update or patch for Dell PowerScale OneFS to address the resource pool vulnerability. If immediate patching is not possible, implement network-level access controls to limit exposure to untrusted networks.

Recommended fix High confidence

Upgrade to 9.1.0.26, 9.2.1.19, or 9.4.0.10 depending on current version branch (minimum fixed version in each respective branch)

  1. Identify the current OneFS version running on the PowerScale cluster (ISI version -q or through the web UI under Cluster > Overview)
  2. Determine which version branch the cluster is currently on (9.1.x, 9.2.x, or 9.4.x)
  3. Plan a maintenance window as OneFS upgrades require cluster downtime
  4. Download the appropriate upgrade ISO from Dell Support (www.dell.com/support) - choose 9.1.0.26 for 9.1.x branches, 9.2.1.19 for 9.2.x branches, or 9.4.0.10 for 9.4.x branches
  5. Review the OneFS upgrade guide and release notes for pre-upgrade checks and prerequisites
  6. Perform a pre-upgrade assessment and backup cluster configuration
  7. Mount the upgrade ISO and initiate the upgrade via 'isi upgrade start' CLI command or through the WebUI
  8. Allow the upgrade to complete; the cluster will reboot as part of the process
Caveat OneFS upgrades require cluster downtime and should be performed during planned maintenance windows; always review release notes for known issues before upgrading
