The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
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
The following non-security bugs were fixed:
