[Oracle Ksplice]

Synopsis: 2.6.32-954.3.5.lve1.4.75.el6 can now be patched using Ksplice
CVEs: CVE-2018-12207 CVE-2019-11135

Systems running CloudLinux 6 can now use Ksplice to patch against the
latest CloudLinux 6 kernel update, 2.6.32-954.3.5.lve1.4.75.el6.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running CloudLinux 6
install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2019-11135: Side-channel information leak in Intel TSX.

A side-channel information leak on some generations of Intel processors
could allow the leaking of internal microarchitectural buffers during
asynchronous aborts in a TSX transaction.  For CPUs that are vulnerable
to Microarchitectural Data Sampling, existing mitigations cover
CVE-2019-11135, for newer CPUs with hardware fixes for MDS, TSX is
transparently disabled.  On these newer CPUs, TSX functionality can be
restored by writing 0 to /sys/kernel/debug/x86/tsx_force_abort.


* Note: Oracle will not be providing a zero downtime update for CVE-2018-12207.

The latest CloudLinux 6 kernel (2.6.32-954.3.5.lve1.4.75.el6) does not
provide a mitigation for CVE-2018-12207.
