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

  - A memory disclosure flaw was found in the Linux kernel's ethernet drivers, in the way it read data from     the EEPROM of the device. This flaw allows a local user to read uninitialized values from the kernel     memory. The highest threat from this vulnerability is to confidentiality. (CVE-2020-14304)

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

The remote OracleVM system is missing necessary patches to address security updates:

  - A memory disclosure flaw was found in the Linux kernel's ethernet drivers, in the way it read data from     the EEPROM of the device. This flaw allows a local user to read uninitialized values from the kernel     memory. The highest threat from this vulnerability is to confidentiality. (CVE-2020-14304)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI     controller. (CVE-2021-32399)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)
