• OpenSSH 10.4 released

    From LWN.net@618:250/24 to All on Tue Jul 7 06:40:09 2026

    OpenSSH 10.4 has been released. In addition to a number of security
    and bug fixes, there are a few notable changes; this release adds
    experimental support for a composite post-quantum signature scheme
    combining ML-DSA 44 and Ed25519 as described in this
    IETF draft. With 10.4, if OpenSSH is compiled with sandbox support
    it will fail on Linux systems that have not enabled SECCOMP
    or NO_NEW_PRIVS; prior to this release, sshd would log an error
    but continue operation. See the release notes for
    a full list of changes.
