The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
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 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)
