#28 False positive on "mismatch" enumeration

[Flash]

I have an enumeration that has a value mismatch. Every reference to this value yields an obtuse warning:

[1] (buffer) mismatch:Function does not check the second iterator for over-read conditions (CWE-126). This functino is often discouraged by most C++ coding standards in favor of its safer alternatives provided since C++14. Consider using a form of this function that checks the second iterator before potentially overflowing it.

I'm guessing the warning is related to std::mismatch() but the whole point of namespace scoping is to disambiguate commonly used names.

class Foo {
public:
    enum MatchState {
        invalid,
        ignored,
        exact_match,
        near_match,
        mismatch,
        match_new,
        mismatch_new,
    };
};
