Service interruption via improper resource release

Published Apr 16, 2026 · Updated Apr 16, 2026

Improper resource shutdown or release in Dell PowerScale OneFS before 9.12.0.0 allows local users with high privileges to interrupt service. Dell has not disclosed the affected component, the resource left open or released incorrectly, or the operation that triggers the condition. Exploitation requires local high-privilege access, and the published impact is limited to availability without identifying whether service hangs, crashes, or reboots.
