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-4302-1 advisory.

    Paulo Bonzini discovered that the KVM hypervisor implementation in the Linux kernel could improperly let a     nested (level 2) guest access the resources of a parent (level 1) guest in certain situations. An attacker     could use this to expose sensitive information. (CVE-2020-2732)

    Gregory Herrero discovered that the fix for CVE-2019-14615 to address the Linux kernel not properly     clearing data structures on context switches for certain Intel graphics processors was incomplete. A local     attacker could use this to expose sensitive information. (CVE-2020-8832)

    It was discovered that the IPMI message handler implementation in the Linux kernel did not properly     deallocate memory in certain situations. A local attacker could use this to cause a denial of service     (kernel memory exhaustion). (CVE-2019-19046)

    It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did not properly deallocate memory     in certain situations. A local attacker could use this to cause a denial of service (kernel memory     exhaustion). (CVE-2019-19051)

    It was discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker could use this to possibly cause a denial of service     (kernel memory exhaustion). (CVE-2019-19056)

    It was discovered that the Intel(R) Wi-Fi device driver in the Linux kernel device driver in the Linux     kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use     this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19058)

    It was discovered that the Brocade BFA Fibre Channel device driver in the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial     of service (kernel memory exhaustion). (CVE-2019-19066)

    It was discovered that the Realtek RTL8xxx USB Wi-Fi device driver in the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial     of service (kernel memory exhaustion). (CVE-2019-19068)

    It was discovered that ZR364XX Camera USB device driver for the Linux kernel did not properly initialize     memory. A physically proximate attacker could use this to cause a denial of service (system crash).
    (CVE-2019-15217)

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.
