The following security bugs were fixed:

CVE-2021-22555: Fixed an heap out-of-bounds write in
 net/netfilter/x_tables.c that could allow local provilege escalation.
 (bsc#1188116)

CVE-2021-33624: Fixed a bug which allows unprivileged BPF program to
 leak the contents of arbitrary kernel memory (and therefore, of all
 physical memory) via a side-channel. (bsc#1187554)

CVE-2021-0605: Fixed an out-of-bounds read which could lead to local
 information disclosure in the kernel with System execution privileges
 needed. (bsc#1187601)

CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to
 local escalation of privilege with no additional execution privileges
 needed. (bsc#1187595)

CVE-2020-26558: Fixed a flaw in the Bluetooth LE and BR/EDR secure
 pairing that could permit a nearby man-in-the-middle attacker to
 identify the Passkey used during pairing. (bnc#1179610)

CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local
 users to obtain sensitive information from kernel stack memory because
 parts of a data structure are uninitialized. (bsc#1187452)

CVE-2021-0129: Fixed an improper access control in BlueZ that may have
 allowed an authenticated user to potentially enable information
 disclosure via adjacent access. (bnc#1186463)

CVE-2020-36386: Fixed an out-of-bounds read in
 hci_extended_inquiry_result_evt. (bsc#1187038)

CVE-2020-24588: Fixed a bug that could allow an adversary to abuse
 devices that support receiving non-SSP A-MSDU frames to inject arbitrary
 network packets. (bsc#1185861 bsc#1185863)

CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer
 that allows to andobtain full root privileges. (bsc#1188062)

CVE-2021-3609: Fixed a race condition in the CAN BCM networking protocol
 which allows for local privilege escalation. (bsc#1187215)

CVE-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for
 local privilege escalation. (bsc#1187050)

CVE-2021-33200: Fix leakage of uninitialized bpf stack under
 speculation. (bsc#1186484)

The following non-security bugs were fixed:

af_packet: fix the tx skb protocol in raw sockets with ETH_P_ALL
 (bsc#1176081).

kabi: preserve struct header_ops after bsc#1176081 fix (bsc#1176081).

net: Do not set transport offset to invalid value (bsc#1176081).

net: Introduce parse_protocol header_ops callback (bsc#1176081).

net/ethernet: Add parse_protocol header_ops support (bsc#1176081).

net/mlx5e: Remove the wrong assumption about transport offset
 (bsc#1176081).

net/mlx5e: Trust kernel regarding transport offset (bsc#1176081).

net/packet: Ask driver for protocol if not provided by user
 (bsc#1176081).

net/packet: Remove redundant skb->protocol set (bsc#1176081).

resource: Fix find_next_iomem_res() iteration issue (bsc#1181193).
