The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel
before 4.14 does not check whether the intended netns is used in a peel-off
action, which allows local users to cause a denial of service
(use-after-free and system crash) or possibly have unspecified other impact
via crafted system calls.
