CVE-2017-7308

Priority
High
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.
Ubuntu-Description
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).
