The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tcp: cdg: allow tcp_cdg_release() to be called multiple times Apparently, mptcp is able to call     tcp_disconnect() on an already disconnected flow. This is generally fine, unless current congestion     control is CDG, because it might trigger a double-free [1] Instead of fixing MPTCP, and future bugs, we     can make tcp_disconnect() more resilient.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-991193 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    Apparently, mptcp is able to call tcp_disconnect() on an already     disconnected flow. This is generally fine, unless current congestion     control is CDG, because it might trigger a double-free [1]

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992803 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    tcp: cdg: allow tcp_cdg_release() to be called multiple times

    Apparently, mptcp is able to call tcp_disconnect() on an already     disconnected flow. This is generally fine, unless current congestion     control is CDG, because it might trigger a double-free [1]

    Instead of fixing MPTCP, and future bugs, we can make tcp_disconnect()     more resilient.
