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-2021-3348: Fixed a use-after-free in nbd_add_socket that could be
 triggered by local attackers (with access to the nbd device) via an I/O
 request at a certain point during device setup (bnc#1181504).

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).

The following non-security bugs were fixed:

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).

ACPI: scan: add stub acpi_create_platform_device() for !CONFIG_ACPI
 (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/via: Add minimum mute flag (git-fixes).

ALSA: hda/via: Fix runtime PM for Clevo W35xSS (git-fixes).

ALSA: pcm: Clear the full allocated memory at hw_params (git-fixes).

ALSA: seq: oss: Fix missing error check in snd_seq_oss_synth_make_info()
 (git-fixes).

ASoC: Intel: haswell: Add missing pm_ops (git-fixes).

ASoC: dapm: remove widget from dirty list on free (git-fixes).

EDAC/amd64: Fix PCI component registration (bsc#1112178).

IB/mlx5: Fix DEVX support for MLX5_CMD_OP_INIT2INIT_QP command
 (bsc#1103991).

KVM: SVM: Initialize prev_ga_tag before use (bsc#1180912).

KVM: x86/mmu: Commit zap of remaining invalid pages when recovering
 lpages (bsc#1181230).

NFS4: Fix use-after-free in trace_event_raw_event_nfs4_set_lock
 (git-fixes).

NFS: nfs_igrab_and_active must first reference the superblock
 (git-fixes).

NFS: switch nfsiod to be an UNBOUND workqueue (git-fixes).

NFSv4.2: condition READDIR's mask for security label based on LSM state
 (git-fixes).

RDMA/addr: ... [Please see the references for more information on the vulnerabilities]");
