| Description: | 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 (overflow) or possibly have unspecified other impact via crafted system calls. Andrey Konovalov discovered that the AF_PACKET implementation in the Linux kernel did not properly validate certain block-size data. A local attacker could use this to cause a denial of service (system crash).
