CVE-2016-4997 high priority: Ubuntu including 32 source packages (linux, linux-armadaxp, …), 239 status rows across 8 suites (artful, precise, trusty, upstream, wily, xenial, yakkety, zesty): DNE 159, released 43, not-affected 19, ignored 18.
The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel before 4.6.3 allow local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement.
