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

CVE-2019-3459, CVE-2019-3460: The Bluetooth stack suffered from two
 remote information leak vulnerabilities in the code that handles
 incoming L2cap configuration packets (bsc#1120758).

CVE-2019-7221: Fixed a use-after-free vulnerability in the KVM
 hypervisor related to the emulation of a preemption timer, allowing an
 guest user/process to crash the host kernel. (bsc#1124732).

CVE-2019-7222: Fixed an information leakage in the KVM hypervisor
 related to handling page fault exceptions, which allowed a guest
 user/process to use this flaw to leak the host's stack memory contents
 to a guest (bsc#1124735).

CVE-2017-18249: The add_free_nid function in fs/f2fs/node.c did not
 properly track an allocated nid, which allowed local users to cause a
 denial of service (race condition) or possibly have unspecified other
 impact via concurrent threads (bnc#1087036).

The following non-security bugs were fixed:
acpi/nfit: Block function zero DSMs (bsc#1123321).

acpi, nfit: Fix ARS overflow continuation (bsc#1125000).

acpi/nfit: fix cmd_rc for acpi_nfit_ctl to always return a value
 (bsc#1124775).

acpi/nfit: Fix command-supported detection (bsc#1123323).

acpi: power: Skip duplicate power resource references in _PRx
 (bnc#1012382).

acpi / processor: Fix the return value of acpi_processor_ids_walk() (git
 fixes (acpi)).

alpha: Fix Eiger NR_IRQS to 128 (bnc#1012382).

alpha: fix page fault handling for r16-r18 targets (bnc#1012382).

alsa: bebob: fix model-id of unit for Apogee Ensemble (bnc#1012382).

alsa: compress: Fix stop handling on compressed capture streams
 (bnc#1012382).

alsa: hda - Add quirk for HP EliteBook 840 G5 (bnc#1012382).

alsa: hda/realtek - Disable headset Mic VREF for headset mode of ALC225
 (bnc#1012382).

alsa: hda - Serialize codec registrations (bnc#1012382).

alsa: usb-audio: Fix implicit fb endpoint setup by quirk (bnc#1012382).

ARC: perf: map generic branches to correct hardware condition
 (bnc#1012382).

arm64: Do not trap host pointer auth use to EL2 (bnc#1012382).

arm64: ftrace: do not adjust the LR value (bnc#1012382).

arm64: hyp-stub: Forbid kprobing of the hyp-stub (bnc#1012382).

arm64/kvm: consistently handle host HCR_EL2 flags ... [Please see the references for more information on the vulnerabilities]");
