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, 8.2.2.x through 9.6.0.x, contains an improper control of a resource through its lifetime vulnerability. An unauthenticated network 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 · high confidence

Dell PowerScale OneFS versions 8.2.2.x through 9.6.0.x contains a resource lifecycle management flaw where the software improperly controls a resource (likely memory, file handles, or network connections) through its lifetime. An unauthenticated remote attacker can exploit this by exhausting the vulnerable resource, causing denial of service.

MitigationApply the Dell-provided security patch for PowerScale OneFS to address the resource lifecycle vulnerability. Upgrade to a patched version within the supported release chain.

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 installed PowerScale OneFS version
    Run the command 'isi version' or 'isi status' on the OneFS CLI, or check the web UI dashboard for the firmware version display
    Affected if The displayed version falls within the range 8.2.2 through 9.6.1 (including any 8.2.2.x and 9.x.x releases up to 9.6.1)
  2. Confirm the exact version number
    Locate the full version string in the CLI output or web UI, noting the major.minor.patch format (for example, 9.0.0, 9.5.2, or 9.6.0)
    Affected if The version starts with 8.2.2 or higher, OR is 9.x.x at any patch level up to and including 9.6.1
  3. Verify the patch state
    Check if Dell support portals or release notes indicate the system is running a post-CVE-2023-44288 patched build, which would typically be version 9.7.0 or later
    Affected if The version remains at 9.6.1 or below with no security patch applied, indicating the vulnerability is present

A system is affected if PowerScale OneFS is running any version from 8.2.2 through 9.6.1 inclusive, as these versions contain the resource lifecycle management flaw that allows unauthenticated remote attackers to cause denial of service through resource exhaustion.

Upgrade available Upgrade to a release after 9.6.1
Interim mitigation

Apply the Dell-provided security patch for PowerScale OneFS to address the resource lifecycle vulnerability. Upgrade to a patched version within the supported release chain.

Recommended fix Moderate confidence

Upgrade to OneFS 9.6.2 or later fixed release

  1. Verify current OneFS version via the web admin console or 'isi version' CLI command
  2. Review Dell PowerScale OneFS upgrade documentation and release notes for version 9.6.2 or later
  3. Schedule a maintenance window as upgrades require cluster downtime
  4. Create a backup of cluster configuration and data
  5. Download the upgrade ISO from Dell Support (support.dell.com)
  6. Upload the upgrade package to the cluster
  7. Execute the upgrade using 'isi upgrade' CLI or through the web admin console
  8. Verify the upgrade completed successfully and all nodes are healthy
Caveat Review release notes for any configuration or compatibility changes between your current version and the target version; some features may behave differently after upgrade
