The following security bugs were fixed:
CVE-2021-45485: Fixed an information leak because of certain use of a
hash table which use IPv6 source addresses. (bsc#1194094)
CVE-2021-45486: Fixed an information leak because the hash table is very
small in net/ipv4/route.c. (bnc#1194087).
CVE-2021-4001: Fixed a race condition when the EBPF map is frozen.
(bsc#1192990)
CVE-2021-28715: Fixed an issue where a guest could force Linux netback
driver to hog large amounts of kernel memory by do not queueing
unlimited number of packages. (bsc#1193442)
CVE-2021-28714: Fixed an issue where a guest could force Linux netback
driver to hog large amounts of kernel memory by fixing rx queue stall
detection. (bsc#1193442)
CVE-2021-28713: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening hvc_xen against event channel
storms. (bsc#1193440)
CVE-2021-28712: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening netfront against event channel
storms. (bsc#1193440)
CVE-2021-28711: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening blkfront against event channel
storms. (bsc#1193440)
CVE-2020-24504: Fixed an uncontrolled resource consumption in some
Intel(R) Ethernet E810 Adapter drivers that may have allowed an
authenticated user to potentially enable denial of service via local
access. (bnc#1182404)
CVE-2021-43975: Fixed a flaw in hw_atl_utils_fw_rpc_wait that could
allow an attacker (who can introduce a crafted device) to trigger an
out-of-bounds write via a crafted length value. (bnc#1192845)
CVE-2021-43976: Fixed a flaw that could allow an attacker (who can
connect a crafted USB device) to cause a denial of service. (bnc#1192847)
CVE-2021-4002: Added a missing TLB flush that could lead to leak or
corruption of data in hugetlbfs. (bsc#1192946)
CVE-2020-27820: Fixed a vulnerability where a use-after-frees in
nouveau's postclose() handler could happen if removing device.

CVE-2021-33098: Fixed a potential denial of service in Intel(R) Ethernet
ixgbe driver due to improper input validation. (bnc#1192877)
The following non-security bugs were fixed:
ACPI: battery: Accept charges over the design capacity as full

ACPI: PMIC: Fix intel_pmic_regs_handler() read accesses (git-fixes).
ACPICA: Avoid evaluating methods too early during system resume
(git-fixes).
ALSA: ctxfi: Fix out-of-range access (git-fixes).
ALSA: gus: fix null pointer dereference on pointer block (git-fixes).
ALSA: hda: hdac_ext_stream: fix potential locking issues (git-fixes).
ALSA: hda: hdac_stream: fix potential locking issue in
snd_hdac_stream_assign() (git-fixes).
ALSA: hda/realtek: Add a quirk for Acer Spin SP513-54N (git-fixes).
