The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4017-1 advisory.

    Jonathan Looney discovered that the TCP retransmission queue implementation in the Linux kernel could be     fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could     use this to cause a denial of service. (CVE-2019-11478)

    Jonathan Looney discovered that an integer overflow existed in the Linux kernel when handling TCP     Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service (system     crash). (CVE-2019-11477)

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

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