Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly requires timely patching of the VF Enable bit write-mask flaw in QEMU's SR-IOV implementation.

CM-7 Least Functionality partial match
prevent

Disables or restricts the PCI SR-IOV feature (and VF Enable) when not required, eliminating the attack surface.

SC-39 Process Isolation minimal match
prevent

Enforces process isolation so a compromised QEMU SR-IOV path cannot affect other VM or host components.

Mitigating Controls (NIST CSF 2.0) AI

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.PS-06 mostly match
prevents

Secure SDLC practices directly enforce spec-compliant functionality and testing, while eliminating this weakness fulfills only part of the control's broader monitoring intent.

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.

A.8.29 Security testing in development and acceptance mostly match
detects

Security testing in development and acceptance validates that implemented functionality conforms to specifications before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle includes requirements and verification activities that directly reduce the risk of delivering functionality that deviates from published specifications.

A.8.26 Application security requirements partial match
prevents

Explicit application security requirements and acceptance criteria help ensure the delivered software matches its intended specifications.

A.8.32 Change management partial match
prevents

Change management processes reduce the chance of unintended functional deviations during updates, though they do not directly address initial specification conformance.
