In the Linux kernel, the following vulnerability has been resolved: mptcp: fastopen: only mark MPTFO subflows with SYN data Passive TCP Fast Open accepts a valid-cookie SYN even when it carries no data. In that case the child socket's receive queue is intentionally left empty. mptcp_fastopen_subflow_synack_set_params() set is_mptfo before checking for queued SYN data. That made data-less TFO SYNs hit a WARN and, if the warning was non-fatal, left stale MPTFO state behind. The stale flag could later trigger a state-confusion bug in check_fully_established(). Only mark the subflow as MPTFO after confirming that an SKB was queued. Return quietly when the receive queue is empty. Note that mptcp_subflow_context's is_mptfo field is now not just about subflows where the TFO was present, but about MPTFO subflow that consumed SYN data. Only having a valid cookie but not carrying data is not really "doing TFO".

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8886-1 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 12 bookworm, these problems have been fixed in version     6.12.107-1~deb12u1.  This update additionally includes many more bug     fixes from stable updates 6.12.102-6.12.107, and adds drivers for     Alcor card readers.

    We recommend that you upgrade your linux-6.12 packages.

    For the detailed security status of linux-6.12 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.12

    Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://wiki.debian.org/LTS     Attachment:

Tenable has extracted the preceding description block directly from the Debian 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - mptcp: fastopen: only mark MPTFO subflows with SYN data Passive TCP Fast Open accepts a valid-cookie SYN     even when it carries no data. In that case the child socket's receive queue is intentionally left empty.
    mptcp_fastopen_subflow_synack_set_params() set is_mptfo before checking for queued SYN data. That made     data-less TFO SYNs hit a WARN and, if the warning was non-fatal, left stale MPTFO state behind. The stale     flag could later trigger a state-confusion bug in check_fully_established(). Only mark the subflow as     MPTFO after confirming that an SKB was queued. Return quietly when the receive queue is empty. Note that     mptcp_subflow_context's is_mptfo field is now not just about subflows where the TFO was present, but about     MPTFO subflow that consumed SYN data. Only having a valid cookie but not carrying data is not really     doing TFO. (CVE-2026-80585)

Note that Nessus relies on the presence of the package as reported by the vendor.
