The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem
in the Linux kernel before 4.6 allows local users to cause a denial of
service (out-of-bounds read) or possibly obtain sensitive information from
kernel heap memory by leveraging in-container root access to provide a
crafted offset value that leads to crossing a ruleset blob boundary.
