The following security bugs were fixed:

CVE-2022-0435: Fixed remote stack overflow in net/tipc module that
 validate domain record count on input (bsc#1195254).

CVE-2021-45095: Fixed refcount leak in pep_sock_accept in
 net/phonet/pep.c (bnc#1193867).

CVE-2022-22942: Fixed stale file descriptors on failed usercopy
 (bsc#1195065).

CVE-2021-22600: Fixed double free bug in packet_set_ring() in
 net/packet/af_packet.c that could have been exploited by a local user
 through crafted syscalls to escalate privileges or deny service
 (bnc#1195184).

CVE-2021-39657: Fixed out of bounds read due to a missing bounds check
 in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local
 information disclosure with System execution privileges needed
 (bnc#1193864).

CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a
 race condition in gadget_dev_desc_UDC_show of configfs.c. This could
 lead to local information disclosure with System execution privileges
 needed. User interaction is not needed for exploitation (bnc#1193861).

CVE-2022-0330: Fixed flush TLBs before releasing backing store
 (bsc#1194880).

The following non-security bugs were fixed:

bpf: Verifer, adjust_scalar_min_max_vals to always call
 update_reg_bounds() (bsc#1194227).

btrfs: tree-checker: Add EXTENT_ITEM and METADATA_ITEM check
 (bsc#1195009).

btrfs: tree-checker: annotate all error branches as unlikely
 (bsc#1195009).

btrfs: tree-checker: check for BTRFS_BLOCK_FLAG_FULL_BACKREF being set
 improperly (bsc#1195009).

hv_netvsc: Set needed_headroom according to VF (bsc#1193506).

net, xdp: Introduce xdp_init_buff utility routine (bsc#1193506).

net, xdp: Introduce xdp_prepare_buff utility routine (bsc#1193506).

net: allow retransmitting a TCP packet if original is still in queue
 (bsc#1188605 bsc#1187428).

net: mana: Add RX fencing (bsc#1193506).

net: mana: Add XDP support (bsc#1193506).

net: sch_generic: avoid concurrent reset and enqueue op for lockless
 qdisc (bsc#1183405).

net: sched: add barrier to ensure correct ordering for lockless qdisc
 (bsc#1183405).

net: sched: avoid unnecessary seqcount operation for lockless qdisc
 (bsc#1183405).

net: sched: fix packet stuck problem for lockless qdisc (bsc#1183405).

net: sched: fix tx action reschedule issue with stopped queue
 (bsc#1183405).

net: sched: fix tx action rescheduling issue during deactivation
 (bsc#1183405).

net: sched: replaced invalid qdisc tree flush helper in qdisc_replace
 (bsc#1183405).

net_sched: avoid resetting active qdisc for multiple times (bsc#1183405).

net_sched: get rid of unnecessary dev_qdisc_reset() (bsc#1183405).

net_sched: use qdisc_reset() in qdisc_destroy() (bsc#1183405).

nvme: add 'iopolicy' module parameter (bsc#1177599 bsc#1193096).

xfrm: fix MTU regression (bsc#1185377, bsc#1194048).");
