  use-after-free flaw was found in the Linux kernel which enables a race condition
  in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to
  escalate their privileges or crash the system. (CVE-2016-10200, Important) * A
  flaw was found that can be triggered in keyring_search_iterator in keyring.c if
  type- match is NULL. A local user could use this flaw to crash the system or,
  potentially, escalate their privileges. (CVE-2017-2647, Important) * It was
  found that the NFSv4 server in the Linux kernel did not properly validate layout
  type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote
  attacker could use this flaw to soft-lockup the system and thus cause denial of
  service. (CVE-2017-8797, Important) This update also fixes multiple Moderate and
  Low impact security issues: * CVE-2015-8839, CVE-2015-8970, CVE-2016-9576,
