ELSA-2017-0294-1 -- Oracle kernel_python-perf_perf
The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel 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.
