"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-000514 advisory.

    Moby is an open source container framework that is a key component of Docker Engine, Docker Desktop, and
    other distributions of container tooling or runtimes. In 26.0.0, IPv6 is not disabled on network
    interfaces, including those belonging to networks where `--ipv6=false`. An container with an `ipvlan` or
    `macvlan` interface will normally be configured to share an external network link with the host machine.
    Because of this direct access, (1) Containers may be able to communicate with other hosts on the local
    network over link-local IPv6 addresses, (2) if router advertisements are being broadcast over the local
    network, containers may get SLAAC-assigned addresses, and (3) the interface  will be a member of IPv6
    multicast groups. This means interfaces in IPv4-only networks present an unexpectedly and unnecessarily
    increased attack surface. The issue is patched in 26.0.2. To completely disable IPv6 in a container, use
    `--sysctl=net.ipv6.conf.all.disable_ipv6=1` in the `docker create` or `docker run` command. Or, in the
    service configuration of a `compose` file.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
