The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331)
- CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)
- CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)
- CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS)
- CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)
This kernel update contains software mitigations for these issues, which also utilize CPU microcode updates shipped in parallel.

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081).
- CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive da
