A certain backport in the TCP Fast Open implementation for the Linux kernel
before 3.18 does not properly maintain a count value, which allow local
users to cause a denial of service (system crash) via the Fast Open
feature, as demonstrated by visiting the
chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through
3.16.x kernel builds, including longterm-maintenance releases and ckt (aka
Canonical Kernel Team) builds.
