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-2019-9213: The expand_downwards function in mm/mmap.c lacked a check
 for the mmap minimum address, which made it easier for attackers to
 exploit kernel NULL pointer dereferences on non-SMAP platforms. This is
 related to a capability check for the wrong task (bnc#1128166).

CVE-2013-0216: The Xen netback functionality allowed guest OS users to
 cause a denial of service (loop) by triggering ring pointer corruption
 (bnc#800280).

CVE-2013-0231: The pciback_enable_msi function in the PCI backend driver
 (drivers/xen/pciback/conf_space_capability_msi.c) in Xen allowed guest
 OS users with PCI device access to cause a denial of service via a large
 number of kernel log messages. (bnc#801178).

CVE-2012-3430: The rds_recvmsg function in net/rds/recv.c did not
 initialize a certain structure member, which allowed local users to
 obtain potentially sensitive information from kernel stack memory via a
 recvfrom or recvmsg system call on an RDS socket (bnc#773383).

CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver allowed remote
 attackers to cause a denial of service (DMA descriptor consumption and
 network-controller outage) via crafted TCP packets that trigger a small
 MSS value (bnc#774523).

CVE-2013-0160: The kernel allowed local users to obtain sensitive
 information about keystroke timing by using the inotify API on the
 /dev/ptmx device (bnc#797175).

CVE-2013-1979: The scm_set_cred function in include/net/scm.h uses
 incorrect uid and gid values during credentials passing, which allowed
 local users to gain privileges via a crafted application (bnc#816708).

The following non-security bugs were fixed:
Add opcodes from net: filter: BPF 'JIT' compiler for PPC64 (bsc#1131107).

EHCI: improved logic for isochronous scheduling (bsc#1117515).

KVM: x86: Use jmp to invoke kvm_spurious_fault() from .fixup
 (bsc#1129439).

USB: Add new USB LPM helpers (bsc#1129770).

USB: Consolidate LPM checks to avoid enabling LPM twice (bsc#1129770).

USB: EHCI: add new root-hub state: STOPPING (bsc#1117515).

USB: EHCI: add pointer to end of async-unlink list (bsc#1117515).

USB: EHCI: add symbolic constants for QHs ... [Please see the references for more information on the vulnerabilities]");
