CVE-2023-25942Network attack vector

Authenticated SMB service interruption via resource exhaustion

Published Apr 4, 2023 · Updated Feb 11, 2025

Uncontrolled resource consumption in Dell PowerScale OneFS 8.2.x through 9.4.x and 9.5.0.0 allows remote authenticated users to interrupt SMB service. Dell identifies SMB as the affected component but has not published the request pattern or resource whose lifetime or consumption is left uncontrolled. A low-privileged network account and SMB reachability are required, and successful exploitation interrupts availability without reported data disclosure or modification.
