  The following security bugs were fixed:

  - CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c
  allowed local users to cause a denial of service (NULL pointer
  dereference and BUG) via crafted system calls that reach a situation
  where ioapic is uninitialized (bnc#1116841).

  - CVE-2018-14625: An attacker might have bene able to have an uncontrolled
  read to kernel-memory from within a vm guest. A race condition between
  connect() and close() function may allow an attacker using the AF_VSOCK
  protocol to gather a 4 byte information leak or possibly intercept or
  corrupt AF_VSOCK messages destined to other clients (bnc#1106615).

  - CVE-2018-19985: The function hso_probe read if_num from the USB device
  (as an u8) and used it without a length check to index an array,
  resulting in an OOB memory read in hso_probe or hso_get_config_data that
  could be used by local attackers (bsc#1120743).

  - CVE-2018-16884: NFS41+ shares mounted in different network namespaces at
  the same time can make bc_svc_process() use wrong back-channel IDs and
  cause a use-after-free vulnerability. Thus a malicious container user
  can cause a host kernel memory corruption and a system panic. Due to the
  nature of the flaw, privilege escalation cannot be fully ruled out
  (bnc#1119946).

  - CVE-2018-20169: The USB subsystem mishandled size checks during the
  reading of an extra descriptor, related to __usb_get_extra_descriptor in
  drivers/usb/core/usb.c (bnc#1119714).

  - CVE-2018-18397: The userfaultfd implementation mishandled access control
  for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users
  to write data into holes in a tmpfs file (if the user has read-only
  access to that file, and that file contains holes), related to
  fs/userfaultfd.c and mm/userfaultfd.c (bnc#1117656).

  - CVE-2018-12232: In net/socket.c there was a race condition between
  fchownat and close in cases where they target the same socket file
  descriptor, related to the sock_close and sockfs_setattr functions.
  fchownat did not increment the file descriptor reference count, which
  allowed close to set the socket to NULL during fchownat's execution,
  leading to a NULL pointer dereference and system crash (bnc#1097593).

  - CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory
  corruption due to type confusion. This could lead to local escalation of
  privilege with no additional execution privileges needed. User
  interaction is not needed for exploitation. (bnc#1118319).
