  The following security bugs were fixed:

  - CVE-2018-10853: A flaw was found in KVM in which certain instructions
  such as sgdt/sidt call segmented_write_std doesn't propagate access
  correctly. As such, during userspace induced exception, the guest can
  incorrectly assume that the exception happened in the kernel and panic
  (bnc#1097104).

  - CVE-2018-10876: A flaw was found in the ext4 filesystem code. A
  use-after-free is possible in ext4_ext_remove_space() function when
  mounting and operating a crafted ext4 image. (bnc#1099811)

  - CVE-2018-10877: Linux kernel ext4 filesystem is vulnerable to an
  out-of-bound access in the ext4_ext_drop_refs() function when operating
  on a crafted ext4 filesystem image. (bnc#1099846)

  - CVE-2018-10878: A flaw was found in the ext4 filesystem. A local user
  can cause an out-of-bounds write and a denial of service or unspecified
  other impact is possible by mounting and operating a crafted ext4
  filesystem image. (bnc#1099813)

  - CVE-2018-10879: A flaw was found in the ext4 filesystem. A local user
  can cause a use-after-free in ext4_xattr_set_entry function and a denial
  of service or unspecified other impact may occur by renaming a file in a
  crafted ext4 filesystem image. (bnc#1099844)

  - CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds
  write in the ext4 filesystem code when mounting and writing to a crafted
  ext4 image in ext4_update_inline_data(). An attacker could use this to
  cause a system crash and a denial of service. (bnc#1099845)

  - CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user
  can cause an out-of-bound access in ext4_get_group_info function, a
  denial of service, and a system crash by mounting and operating on a
  crafted ext4 filesystem image. (bnc#1099864)

  - CVE-2018-10882: A flaw was found in the ext4 filesystem. A local user
  can cause an out-of-bound write in in fs/jbd2/transaction.c code, a
  denial of service, and a system crash by unmounting a crafted ext4
  filesystem image. (bnc#1099849)

  - CVE-2018-10883: A flaw was found in the ext4 filesystem. A local user
  can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a
  denial of service, and a system crash by mounting and operating on a
  crafted ext4 filesystem image. (bnc#1099863)

  - CVE-2018-3620: Systems with microprocessors utilizing speculative
  execution and address translations may allow unauthorized disclosure of
  information residing in the L1 data cache to an attacker with local user
  access  ...
