Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-7308 high priority: Ubuntu including 32 source packages (linux, linux-armadaxp, …), 216 status rows across 7 suites (artful, precise, trusty, upstream, xenial, yakkety, zesty): DNE 145, released 49, ignored 11, not-affected 11.
The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to cause a denial of service (integer signedness error and out-of-bounds write), or gain privileges (if the CAP_NET_RAW capability is held), via crafted system calls.
