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-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial
 of service (system crash) because there is a race condition between
 direct and memory-mapped I/O (associated with a hole) that is handled
 with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010).

CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can
 be triggered leading to a kernel panic (bnc#1071021).

CVE-2017-16533: The usbhid_parse function in
 drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of
 service (out-of-bounds read and system crash) or possibly have
 unspecified other impact via a crafted USB device (bnc#1066674).

CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c
 allowed physically proximate attackers to cause a denial of service
 (integer underflow) or possibly have unspecified other impact via a
 crafted HID report (bnc#1031240).

CVE-2017-7472: The KEYS subsystem allowed local users to cause a denial
 of service (memory consumption) via a series of
 KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls
 (bnc#1034862).

CVE-2018-14633: A security flaw was found in the
 chap_server_compute_md5() function in the ISCSI target code in the Linux
 kernel in a way an authentication request from an ISCSI initiator is
 processed. An unauthenticated remote attacker can cause a stack buffer
 overflow and smash up to 17 bytes of the stack. The attack requires the
 iSCSI target to be enabled on the victim host. Depending on how the
 target's code was built (i.e. depending on a compiler, compile flags and
 hardware architecture) an attack may lead to a system crash and thus to
 a denial-of-service or possibly to a non-authorized access to data
 exported by an iSCSI target. (bnc#1107829).

CVE-2018-15572: The spectre_v2_select_mitigation function in
 arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context
 switch, which made it easier for attackers to conduct
 userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at
 the same time can make bc_svc_process() use wrong ... [Please see the references for more information on the vulnerabilities]");
