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.

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)
