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

  - In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum     address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP     platforms. This is related to a capability check for the wrong task. (CVE-2019-9213)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

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