Vulnerability Data
The ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars (a scalar larger than the order of the curve). This does not impact usages of crypto/ecdsa or crypto/ecdh.

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.
Secure development lifecycle mandates verification steps that catch incorrect calculations before they reach production.
A.8.26 requires that security requirements (including resilience against attacks such as buffer overflows or SQL injection) be identified during development or acquisition; it does not itself enforce correct calculations or stop an arithmetic error from being introduced or exploited.
A.8.27 mandates establishing and applying secure engineering principles (including secure-by-design, least privilege, and design reviews) but does not itself remove or rewrite an incorrect calculation already present in first-party code; that is a code defect class reached only by testing or remediation controls per the locus rule.
Secure coding standards directly prohibit unsafe arithmetic and require defensive checks against incorrect results.
Security testing in development and acceptance can detect calculation flaws before deployment.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-682, a pillar-level weakness, and none of its children carries one either.
