CVE-2022-23159Network attack vector

Authenticated denial of service via unreleased memory

Published Apr 12, 2022 · Updated Sep 17, 2024

Memory-release failure in Dell PowerScale OneFS 8.2.2 through 9.3.0.x allows remote authenticated users to interrupt cluster service. Dell identifies unreleased memory after its effective lifetime but does not disclose the affected process, request, or input that retains each allocation. Exploitation requires SSH or console login privilege plus ISI_PRIV_AUTH_PROVIDERS, and the denial of service can affect Compliance-mode clusters.
