RHSA-2017:0294: Important: kernel security update
First published: Wed Feb 22 2017(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>Security Fix(es):<br><li> 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 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. (CVE-2017-6074, Important)</li>
