arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in
the Linux kernel through 3.18.1 allows local users to bypass the espfix
protection mechanism, and consequently makes it easier for local users to
bypass the ASLR protection mechanism, via a crafted application that makes
a set_thread_area system call and later reads a 16-bit value.
