Red Hat Security Advisory 2017-0403-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol implementation freed SKB resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
