    In view of recent discussions on Debian lists for big-endian systems
    about the problem of undesirable little-endian assumptions in some
    software packages, this snippet from a posting to the [email protected] may be of interest:

    Hi,

    This is mostly a note for downstream distributors of OpenSSH. I've
    just pushed fixes to the V_9_9 stable branch for a bug in the
    mlkem768x25519-sha256 key exchange algorithm that was added in this
    release that causes connection failures when connecting between
    big-endian and little-endian hosts.

    The problem is on the big-endian side. No change is required for
    the more common little-endian architectures (e.g. x86, ARM).

    If you distribute OpenSSH to big-endian systems and have packaged
    OpenSSH 9.9 already, then I recommend you include these fixes as the
    next release of OpenSSH will make this key exchange algorithm the
    default.

    Thanks,
    Damien
