The following security bugs were fixed:

CVE-2021-3347: A use-after-free was discovered in the PI futexes during
 fault handling, allowing local users to execute code in the kernel
 (bnc#1181349).

CVE-2021-20177: Fixed a kernel panic related to iptables string matching
 rules. A privileged user could insert a rule which could lead to denial
 of service (bnc#1180765).

CVE-2021-0342: In tun_get_user of tun.c, there is possible memory
 corruption due to a use after free. This could lead to local escalation
 of privilege with System execution privileges required. (bnc#1180812)

CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was
 found, specifically in the way user calls Ioctl after open dev file and
 fork. A local user could use this flaw to crash the system (bnc#1179878).

CVE-2020-25639: Fixed a NULL pointer dereference via nouveau ioctl
 (bnc#1176846).

CVE-2020-29569: Fixed a potential privilege escalation and information
 leaks related to the PV block backend, as used by Xen (bnc#1179509).

CVE-2020-29568: Fixed a denial of service issue, related to processing
 watch events (bnc#1179508).

CVE-2020-36158: Fixed an issue wich might have allowed a remote
 attacker to execute arbitrary code via a long SSID value in
 mwifiex_cmd_802_11_ad_hoc_start() (bnc#1180559).

CVE-2020-28374: Fixed a vulnerability caused by insufficient identifier
 checking in the LIO SCSI target code. This could have been used by a
 remote attacker to read or write files via directory traversal in an
 XCOPY request (bnc#1178372).

The following non-security bugs were fixed:

ACPICA: Disassembler: create buffer fields in ACPI_PARSE_LOAD_PASS1
 (git-fixes).

ACPICA: Do not increment operation_region reference counts for field
 units (git-fixes).

ACPI: PNP: compare the string length in the matching_id() (git-fixes).

ACPI: scan: add stub acpi_create_platform_device() for !CONFIG_ACPI
 (git-fixes).

ACPI: scan: Harden acpi_device_add() against device ID overflows
 (git-fixes).

ACPI: scan: Make acpi_bus_get_device() clear return pointer on error
 (git-fixes).

ALSA: ca0106: fix error code handling (git-fixes).

ALSA: ctl: allow TLV read operation for callback type of element in
 locked case (git-fixes).

ALSA: doc: Fix reference to mixart.rst (git-fixes).

ALSA: fireface: Fix integer overflow in transmit_midi_msg() (git-fixes).

ALSA: firewire-tascam: Fix integer overflow in midi_port_work()
 (git-fixes).

ALSA: hda: Add NVIDIA codec IDs 9a & 9d through a0 to patch table
 (git-fixes).

ALSA: hda: Fix potential race in unsol event handler (git-fixes).

ALSA: hda - Fix silent audio output and corrupted input on MSI X570-A
 PRO (git-fixes).

ALSA: hda/generic: Add option to enforce preferred_dacs pairs
 (git-fixes).

ALSA: hda/hdmi: always check pin power status in i915 pin fixup
