OL5 and OL6 install these updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

# /usr/sbin/uptrack-upgrade -y
* CVE-2016-3157: Xen I/O port access privilege escalation in x86-64.
User mode processes not supposed to be able to access I/O ports may
be granted such permission, potentially resulting in one or more of
in-guest privilege escalation, guest crashes (Denial of Service), or
in-guest information leaks.
* CVE-2016-7117: Denial-of-service in recvmmsg() error handling.
Incorrect reference counting could result in a use-after-free in the
recvmmsg() system call. A local, unprivileged user could use this flaw
to trigger a denial-of-service.
Ksplice support is available at ksplice-support_ww at oracle.com.
