The following security bugs were fixed:

CVE-2021-22555: A heap out-of-bounds write was discovered in
 net/netfilter/x_tables.c (bnc#1188116).

CVE-2021-33909: Extremely large seq buffer allocations in seq_file could
 lead to buffer underruns and code execution (bsc#1188062).

CVE-2021-3609: A use-after-free in can/bcm could have led to privilege
 escalation (bsc#1187215).

CVE-2021-3612: An out-of-bounds memory write flaw was found in the
 joystick devices subsystem in the way the user calls ioctl JSIOCSBTNMAP.
 This flaw allowed a local user to crash the system or possibly escalate
 their privileges on the system. The highest threat from this
 vulnerability is to confidentiality, integrity, as well as system
 availability (bnc#1187585 ).

CVE-2021-35039: kernel/module.c mishandled Signature Verification, aka
 CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel
 module is signed, for loading via init_module, did not occur for a
 module.sig_enforce=1 command-line argument (bnc#1188080). NOTE that SUSE
 kernels are configured with CONFIG_MODULE_SIG=y, so are not affected.

The following non-security bugs were fixed:

ACPI: APEI: fix synchronous external aborts in user-mode (git-fixes).

ACPI: bus: Call kobject_put() in acpi_init() error path (git-fixes).

ACPICA: Fix memory leak caused by _CID repair function (git-fixes).

ACPI: EC: Make more Asus laptops use ECDT _GPE (git-fixes).

ACPI: processor idle: Fix up C-state latency if not ordered (git-fixes).

ACPI: property: Constify stubs for CONFIG_ACPI=n case (git-fixes).

ACPI: resources: Add checks for ACPI IRQ override (git-fixes).

ACPI: sysfs: Fix a buffer overrun problem with description_show()
 (git-fixes).

ALSA: hda/realtek: Add another ALC236 variant support (git-fixes).

ALSA: hda/realtek: Fix bass speaker DAC mapping for Asus UM431D
 (git-fixes).

ALSA: intel8x0: Fix breakage at ac97 clock measurement (git-fixes).

ALSA: isa: Fix error return code in snd_cmi8330_probe() (git-fixes).

ALSA: usb-audio: fix rate on Ozone Z90 USB headset (git-fixes).

ALSA: usb-audio: scarlett2: Fix wrong resume call (git-fixes).

ALSA: usb-audio: scarlett2: Read mixer volumes at init time (git-fixes).

ALSA: usb-audio: scarlett2: Read mux at init time (git-fixes).

amdgpu: fix GEM obj leak in amdgpu_display_user_framebuffer_create
 (bsc#1152472)

ASoC: atmel-i2s: Fix usage of capture and playback at the same time
 (git-fixes).

ASoC: cs42l42: Correct definition of CS42L42_ADC_PDN_MASK (git-fixes).

ASoC: hisilicon: fix missing clk_disable_unprepare() on error in
 hi6210_i2s_startup() (git-fixes).

ASoC: mediatek: mtk-btcvsd: Fix an error handling path in
 'mtk_btcvsd_snd_probe()' (git-fixes).

ASoC: rsnd: tidyup loop on rsnd_adg_clk_query() (git-fixes).

ata: ahci_sunxi: Disable DIPM (git-fixes).
