    And we may only be beginning to realize how much of the iceberg is still below the surface... 😄

    I confess, I posted this because I think *SSHOLE is a really good buzzword for 2026. 😄

    Thanks for sharing this, ​@Nancy OShea .

    One important point worth emphasizing is that this vulnerability does not affect all OpenSSH installations. It requires a specific combination of conditions, particularly a musl-based Linux environment, OpenSSH running without PAM, password authentication enabled, and certain account configurations.

    OpenSSH 10.6p2 addresses the issue, and patched packages are also available for Alpine Linux.

    In case, for [ administrators ] maintaining affected servers, as required by the notes, the priority is to apply the available security updates. Disabling SSH password authentication is also a possible mitigation when an immediate update is not feasible [ /administrators ].
