The following security bugs were fixed:
CVE-2019-2024: A use-after-free when disconnecting a source was fixed
 which could lead to crashes. bnc#1129179).

CVE-2019-9213: expand_downwards 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-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. (bnc#1107829).

CVE-2019-7221: The KVM implementation in the Linux kernel had a
 Use-after-Free (bnc#1124732).

CVE-2019-7222: The KVM implementation in the Linux kernel had an
 Information Leak (bnc#1124735).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled
 reference counting because of a race condition, which led to a
 use-after-free (bnc#1124728).

The following non-security bugs were fixed:
copy_mount_string: Limit string length to PATH_MAX (bsc#1082943).

enic: add wq clean up budget (bsc#1075697, bsc#1120691. bsc#1102959).

ibmvscsi: Fix empty event pool access during host removal (bsc#1119019).

ipv4: ipv6: Adjust the frag mem limit after truesize has been changed
 (bsc#1110286).

kmps: obsolete older KMPs of the same flavour (bsc#1127155, bsc#1109137).

netfilter: ipv6: Adjust the frag mem limit after truesize has been
 changed (bsc#1110286).

perf/x86: Add sysfs entry to freeze counters on SMI (bsc#1121805).

perf/x86/intel: Delay memory deallocation until x86_pmu_dead_cpu()
 (bsc#1121805).

perf/x86/intel: Do not enable freeze-on-smi for PerfMon V1 (bsc#1121805).

perf/x86/intel: Fix memory corruption (bsc#1121805).

perf/x86/intel: Generalize dynamic constraint creation (bsc#1121805).

perf/x86/intel: Implement support for TSX Force Abort (bsc#1121805).

perf/x86/intel: Make cpuc allocations consistent (bsc#1121805).

pseries/energy: Use OF accessor function to read ibm,drc-indexes
 (bsc#1129080).

restore cond_resched() in shrink_dcache_parent() (bsc#1098599,
 bsc#1105402, bsc#1127758).

rps: flow_dissector: Fix uninitialized flow_keys used in __skb_get_hash
 possibly (bsc#1108145).

scsi: megaraid_sas: Send SYNCHRONIZE_CACHE for VD to firmware
 (bsc#1121698).

scsi: sym53c8xx: fix NULL pointer dereference panic in sym_int_sir()
 (bsc#1125315).

x86: Add TSX Force Abort CPUID/MSR (bsc#1121805).

x86: respect memory size limiting via mem= parameter (bsc#1117645).

x86/spectre_v2: Do not check microcode versions when running under
 hypervisors (bsc#1122821).

x86/xen: dont add memory above max allowed allocation (bsc#1117645).

xen-netfront: Fix hang on device removal (bnc#1012382).

xfrm: use complete IPv6 addresses for ... [Please see the references for more information on the vulnerabilities]");
