The SUSE Linux Enterprise 12 SP2 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 following security bugs were fixed:
- CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network could use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. (bnc#1096748).
- CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. (bnc#1096748).
- CVE-2016-8636: Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c allowed local users to cause a denial of service (memory corruption), obtain sensitive information or possibly have unspecified other impact via a write or read request involving the 'RDMA protocol over infiniband' (aka Soft RoCE) technology (bnc#1024908).
- CVE-2017-18174: In the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).
- CVE-2018-1091: In the flush_tmregs_to_thread function in...
