summary: Incorrect calculation on P256 curves in crypto/internal/nistec
description: |-
    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.
