RHSA-2017:0293: Important: kernel security update
The kernel packages contain the Linux kernel, the core of any Linux operating system.Security Fix(es): A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCPPKTREQUEST packet when the IPV6RECVPKTINFO 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. (CVE-2017-6074, Important)
