The following security bugs were fixed:
CVE-2018-20855: An issue was discovered in create_qp_common,
 mlx5_ib_create_qp_resp was never initialized, resulting in a leak of
 stack memory to userspace. (bnc#bsc#1103991)

CVE-2019-1125: Fix Spectre V1 variant via swapgs: Exclude ATOMs from
 speculation through SWAPGS (bsc#1139358).

CVE-2019-14284: In the Linux kernel, drivers/block/floppy.c allowed a
 denial of service by setup_format_params division-by-zero.
 (bnc#bsc#1143189)

CVE-2019-14283: In the Linux kernel, set_geometry in
 drivers/block/floppy.c did not validate the sect and head fields, as
 demonstrated by an integer overflow and out-of-bounds read. It can be
 triggered by an unprivileged local user when a floppy disk has been
 inserted. NOTE: QEMU creates the floppy device by default. (bsc#1143191)

CVE-2019-11810: An issue was discovered in the Linux kernel A NULL
 pointer dereference can occur when megasas_create_frame_pool() fails in
 megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This
 causes a Denial of Service, related to a use-after-free. (bsc#1134399)

CVE-2019-13648: In the Linux kernel on the powerpc platform, when
 hardware transactional memory was disabled, a local user can cause a
 denial of service via a sigreturn() system call that sends a crafted
 signal frame. (bnc#1142265)

CVE-2019-13631: In parse_hid_report_descriptor, a malicious usb device
 could send an hid: report that triggered an out-of-bounds write during
 generation of debugging messages. (bnc#1142023)

The following non-security bugs were fixed:
acpi/nfit: Always dump _DSM output payload (bsc#1142351).

acpi: PM: Allow transitions to D0 to occur in special cases
 (bsc#1051510).

acpi: PM: Avoid evaluating _PS3 on transitions from D3hot to D3cold
 (bsc#1051510).

af_unix: remove redundant lockdep class (git-fixes).

alsa: compress: Be more restrictive about when a drain is allowed
 (bsc#1051510).

alsa: compress: Do not allow partial drain operations on capture
 streams (bsc#1051510).

alsa: compress: Fix regression on compressed capture streams
 (bsc#1051510).

alsa: compress: Prevent bypasses of set_params (bsc#1051510).

alsa: hda - Add a conexant codec entry to let mute led work
 (bsc#1051510).

alsa: hda/realtek - Fixed Headphone Mic can't record on Dell platform
 (bsc#1051510).

alsa: hda/realtek - Headphone Mic can't record after S3 (bsc#1051510).

alsa: hda/realtek: apply ALC891 headset fixup to one Dell machine
 (bsc#1051510).

alsa: line6: Fix a typo (bsc#1051510).

alsa: line6: Fix wrong altsetting for LINE6_PODHD500_1 (bsc#1051510).

alsa: seq: Break too long mutex context in the write loop (bsc#1051510).

alsa: usb-audio: Add quirk for Focusrite Scarlett Solo (bsc#1051510).

alsa: usb-audio: Add quirk for MOTU MicroBook II (bsc#1051510).
