Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2017-6074
CWEhttps://cwe.mitre.org/data/definitions/415.html

The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to obtain root privileges or cause a denial of service (double free) via an application that makes an IPV6_RECVPKTINFO setsockopt system call.

Weakness

The product calls free() twice on the same memory address.
