This is a proof-of-concept Local Privelege Escalation exploit for CVE-2017-6074 — a double-free vulnerability I found in the Linux kernel DCCP sockets. Includes semireliable SMEP and SMAP bypass (the kernel might crash shorty after the exploit succeds). See the details in CVE-2017-6074: Exploiting a double-free in the Linux kernel DCCP sockets.
