CVE-2022-46679Network attack vector

Unauthenticated service interruption via resource exhaustion

Published Feb 1, 2023 · Updated Mar 26, 2025

Insufficient resource pool handling in Dell PowerScale OneFS 8.2.x and 9.0.0.x through 9.4.0.x allows remote attackers to interrupt service. Dell identifies an undersized resource pool but has not published the affected service, resource type, request path, or exhaustion operation. No authentication or user interaction is required, but the undisclosed failure mode prevents distinguishing a hang, crash, reboot, or narrower outage.
