CVE-2025-30101
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 · uneditedDell PowerScale OneFS, versions 9.8.0.0 through 9.10.1.0, contain a time-of-check time-of-use (TOCTOU) race condition vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to denial of service and information tampering.
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 confidenceDell PowerScale OneFS versions 9.8.0.0 through 9.10.1.0 contain a time-of-check time-of-use (TOCTOU) race condition vulnerability. An unauthenticated attacker with local physical or console access can exploit the time gap between a security check and resource use, potentially causing denial of service and information tampering.

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 checksWork through these to decide whether this CVE applies to you.
-
Check PowerScale OneFS versionRun 'isi version' or 'isi cluster nodes' from the command line to display the installed OneFS versionAffected if The displayed version falls between 9.8.0.0 and 9.10.1.0 inclusive, or shows 9.10.1.1 or lower
-
Confirm version is within vulnerable rangeCompare the installed version number to the affected range: versions 9.8.0.0 through 9.10.1.0 are vulnerable. Versions 9.10.1.2 and later are not affectedAffected if Installed version is 9.8.0.0, 9.8.0.x, 9.9.x.x, 9.10.0.x, 9.10.1.0, or 9.10.1.1
-
Assess physical/console access exposureReview whether the system has untrusted local physical access or exposed console ports. Check network segmentation and physical security controls around the storage arrayAffected if Untrusted individuals have or could obtain local physical or console access to the PowerScale nodes
-
Review system audit logs for console accessExamine /var/log/ messages and isi audit logs for unusual or unauthorized console login attempts, especially during maintenance windows or after-hours activityAffected if Unexpected or unauthorized console access events are found in system logs
You are affected if your PowerScale OneFS version is 9.8.0.0 through 9.10.1.1 and untrusted local physical or console access to the system is possible.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped9.10.1.2
Apply Dell-provided patches to upgrade PowerScale OneFS beyond version 9.10.1.0. Until patches are applied, restrict local physical and console access to the storage system and monitor for suspicious local access attempts.
9.10.1.2 or later
- Review the Dell PowerScale OneFS upgrade documentation at dell.com/support
- Plan upgrade during maintenance window given potential for denial of service
- Download OneFS version 9.10.1.2 or later from Dell support portal
- Follow standard OneFS upgrade procedure: backup configuration, verify cluster health, apply upgrade
- After upgrade, verify cluster is operational and the vulnerability is remediated
