Description

Security Fix(es):

• A use-after-free flaw was found in the way the Linux kernel's Datagram
  Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer)
  resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set
  on the socket. A local, unprivileged user could use this flaw to alter the
  kernel memory, allowing them to escalate their privileges on the system.
  (CVE-2017-6074, Important)
