CVE-2017-7308
Published: 29 March 2017
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.
From the Ubuntu Security Team
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).
