CVE-2026-63690Hinoki check available

Adjacent-network information disclosure via missing authentication

Published Oct 6, 2026 · Updated Oct 6, 2026

Missing authentication in Dell Container Storage Modules before 1.18.0 allows remote attackers on an adjacent network to read CSI driver information. The PowerFlex, PowerMax, and PowerStore CSI drivers leave a critical function without caller authentication; Dell has not identified that function or the information it returns. Exploitation requires adjacent-network reachability to an affected driver; write access and storage-array takeover are not established for this CVE.
