The sample userspace firmware-management tool uses strncpy() to copy firmware tags. strncpy() does not guarantee null-termination and can leave buffers unterminated. For userspace code, strlcpy() is the recommended safe alternative.

Replace all strncpy() calls with strlcpy().

Don't use strlcpy(). Either use strscpy() or strscpy_pad() as appropriate. I wrote a blog about this which may be useful.
