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.
