CVE-2017-6347

The ip_cmsg_recv_checksum function in net/ipv4/ip_sockglue.c in the Linux kernel before 4.10.1 has incorrect expectations about skb data layout, which allows local users to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted system calls, as demonstrated by use of the MSG_MORE flag in conjunction with loopback UDP transmission.

From the Ubuntu Security Team

Andrey Konovalov discovered that the IP layer in the Linux kernel made improper assumptions about internal data layout when performing checksums. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
