Local privilege escalation
Published Mar 4, 2026 · Updated Mar 4, 2026
Incorrect privilege assignment in Dell PowerScale OneFS before 9.10.1.6 and 9.11.0.0 through 9.12.0.1 allows local users to elevate privileges. Dell identifies the defect only as incorrect privilege assignment and has not disclosed the affected component or the operation that assigns excessive privileges. Exploitation requires existing low-privileged local access, high attack complexity, and user interaction, and can compromise confidentiality, integrity, and availability.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=9.11.0.0 through 9.12.0.1 <9.13.0.0 or later
- Affected versionversion=prior to 9.10.1.6 <9.10.1.6 or later
