CVE-2026-40641 is a medium-severity Use of a Broken or Risky Cryptographic Algorithm (CWE-327) vulnerability in Dell Powerflex Manager. Its CVSS base score is 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires use of approved cryptographic algorithms and modules, eliminating the broken algorithm (CWE-327) that enables disclosure/tampering.
Mandates timely flaw remediation and patching, directly addressing the vulnerable PowerFlex Manager versions prior to 5.1.0.1.
Requires cryptographic protection of transmitted information to prevent disclosure and tampering over remote connections.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.DS-01 promotes encryption for data-at-rest but never requires strong algorithms, leaving CWE-327 fully possible; the weakness is also far broader than data-at-rest so one narrow control removes none of its total risk.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.
The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.
Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.
