Description

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes. This update is only provided as a fix update for IBM Z platform.

  • CVE-2017-5753 / 'Spectre Attack': IBM Z fixes were included but not enabled in the previous update. This update enables those fixes.

  • CVE-2017-5715 / 'Spectre Attack': IBM Z fixes were already included in the previous update. A bugfix for the patches has been applied on top.

  • CVE-2017-5754: The IBM Z architecture is not affected by the 'Meltdown' attack.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
