    net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a
    denial of service (system crash) via (1) an application that made
    crafted system calls or possibly (2) IPv4 traffic with invalid IP
    options (bsc#1025013).
    - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in
    the Linux kernel did not properly validate certain block-size data,
    which allowed local users to cause a denial of service (overflow) or
    possibly have unspecified other impact via crafted system calls
    (bsc#1030575, bsc#1031660).
