fs/eventpoll.c in the Linux kernel before 2.6.38 places epoll file
descriptors within other epoll data structures without properly
checking for (1) closed loops or (2) deep chains, which allows local
users to cause a denial of service (deadlock or stack memory
consumption) via a crafted application that makes epoll_create and
epoll_ctl system calls.
