The following security bugs were fixed:

CVE-2019-9003: Attackers can trigger a
 drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging
 for certain simultaneous execution of the code, as demonstrated by a
 'service ipmievd restart' loop (bnc#1126704).

CVE-2018-16880: A flaw was found in the handle_rx() function in the
 [vhost_net] driver. A malicious virtual guest, under specific
 conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a
 virtual host which may lead to a kernel memory corruption and a system
 panic. Due to the nature of the flaw, privilege escalation cannot be
 fully ruled out. (bnc#1122767).

CVE-2019-9500: A brcmfmac heap buffer overflow in brcmf_wowl_nd_results
 was fixed. (bnc#1132681).

CVE-2019-9503: A brcmfmac frame validation bypass was fixed.
 (bnc#1132828).

CVE-2019-3882: A flaw was found in the vfio interface implementation
 that permits violation of the user's locked memory limit. If a device is
 bound to a vfio driver, such as vfio-pci, and the local attacker is
 administratively granted ownership of the device, it may cause a system
 memory exhaustion and thus a denial of service (DoS). (bnc#1131416
 bnc#1131427).

The following non-security bugs were fixed:

9p: do not trust pdu content for stat item size (bsc#1051510).

acpi: acpi_pad: Do not launch acpi_pad threads on idle cpus
 (bsc#1113399).

acpi, nfit: Prefer _DSM over _LSR for namespace label reads
 (bsc#1132426).

acpi / SBS: Fix GPE storm on recent MacBookPro's (bsc#1051510).

alsa: core: Fix card races between register and disconnect (bsc#1051510).

alsa: echoaudio: add a check for ioremap_nocache (bsc#1051510).

alsa: firewire: add const qualifier to identifiers for read-only symbols
 (bsc#1051510).

alsa: firewire-motu: add a flag for AES/EBU on XLR interface
 (bsc#1051510).

alsa: firewire-motu: add specification flag for position of flag for
 MIDI messages (bsc#1051510).

alsa: firewire-motu: add support for MOTU Audio Express (bsc#1051510).

alsa: firewire-motu: add support for Motu Traveler (bsc#1051510).

alsa: firewire-motu: use 'version' field of unit directory to identify
 model (bsc#1051510).
