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.

  - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a     malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)

  - A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because     an attacker cannot realistically control this failure at probe time (CVE-2019-19046)

  - A memory leak in the i2400m_op_rfkill_sw_toggle() function in drivers/net/wimax/i2400m/op-rfkill.c in the     Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption), aka     CID-6f3ef5c25cc7. (CVE-2019-19051)

  - A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in     drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allows attackers to cause a     denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-     db8fd2cde932. (CVE-2019-19056)

  - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)

  - A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     bfa_port_get_stats() failures, aka CID-0e62395da2bd. (CVE-2019-19066)

  - A memory leak in the rtl8xxxu_submit_int_urb() function in     drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c in the Linux kernel through 5.3.11 allows attackers     to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka     CID-a2cdd07488e6. (CVE-2019-19068)

  - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest     when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)

  - The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 (The Linux kernel did not properly     clear data structures on context switches for certain Intel graphics processors.) was discovered to be     incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this     vulnerability to expose sensitive information. (CVE-2020-8832)

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