______________________________________________________________________________
An update that solves 6 vulnerabilities and has 30 fixes is
now available.
Description:
The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
race condition in the Instruction Fetch Unit of the Intel CPU to cause a
Machine Exception during Page Size Change, causing the CPU core to be
non-functional.
The Linux Kernel KVM hypervisor was adjusted to avoid page size changes in
executable pages by splitting / merging huge pages into small pages as
needed. More information can be found on
https://www.suse.com/support/kb/doc/?id=7023735
CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with
Transactional Memory support could be used to facilitate sidechannel
information leaks out of microarchitectural buffers, similar to the
previously described "Microarchitectural Data Sampling" attack.
The Linux kernel was supplemented with the option to disable TSX operation
altogether (requiring CPU Microcode updates on older systems) and better
flushing of microarchitectural buffers (VERW).
The set of options available is described in our TID at
https://www.suse.com/support/kb/doc/?id=7024251
