If the person on windows has set core.autocrlf = true this will ensure
that the checked in files are LF terminated. With core.autocrlf = true
CRLF files cannot enter the repository, but it's important that every
windows user sets core.autocrlf to true.

If the person on windows hasn't set that variable the CRLF files will
enter the repository. If someone on linux with core.autocrlf = input
checks out those files they will be fixed to LF endings automatically -
which imho is a good thing. Because of that the files will be shown as
changed(They now have different line endings as in the repository. This
is a change and needs to be commited). If you don't want git to fix that
automatically just use core.autocrlf = false on linux.
