  propagated security sensitive extended attributes, such as
  POSIX ACLs. A local unprivileged attacker could use this to gain
  privileges. (CVE-2016-1575)

  It was discovered that the Linux kernel keyring subsystem contained a race

  not validate protocol identifiers for certain protocol families, A local
  attacker could use this to cause a denial of service (system crash) or
  possibly gain administrative privileges. (CVE-2015-8543)

  Dmitry Vyukov discovered that the pptp implementation in the Linux kernel
  did not verify an address length when setting up a socket. A local attacker
  could use this to craft an application that exposed sensitive information
  from kernel memory. (CVE-2015-8569)

  kernel did not properly validate the socket address length for Synchronous
  Connection-Oriented (SCO) sockets. A local attacker could use this to
  expose sensitive information. (CVE-2015-8575)

  It was discovered that the Linux kernel's Filesystem in Userspace (FUSE)
  implementation did not handle initial zero length segments properly. A

  task). (CVE-2015-8785)");
