The following security bugs were fixed:

CVE-2022-3303: Fixed a race condition in the sound subsystem due to
 improper locking (bnc#1203769).

CVE-2022-41218: Fixed an use-after-free caused by refcount races in
 drivers/media/dvb-core/dmxdev.c (bnc#1202960).

CVE-2022-3239: Fixed an use-after-free in the video4linux driver that
 could lead a local user to able to crash the system or escalate their
 privileges (bnc#1203552).

CVE-2022-2503: Fixed a bug in dm-verity, device-mapper table reloads
 allowed users with root privileges to switch out the target with an
 equivalent dm-linear target and bypass verification till reboot. This
 allowed root to bypass LoadPin and can be used to load untrusted and
 unverified kernel modules and firmware, which implies arbitrary kernel
 execution and persistence for peripherals that do not verify firmware
 updates (bnc#1202677).

CVE-2022-39188: Fixed a race condition where a device driver can free a
 page while it still has stale TLB entries. (bnc#1203107).

CVE-2022-2663: Fixed an issue which allowed a firewall to be bypassed
 when users are using unencrypted IRC with nf_conntrack_irc configured
 (bnc#1202097).

The following non-security bugs were fixed:

dtb: Do not include sources in src.rpm - refer to kernel-source Same as
 other kernel binary packages there is no need to carry duplicate sources
 in dtb packages.

net: mana: Add rmb after checking owner bits (git-fixes).

net: mana: Add the Linux MANA PF driver (bug#1201309, jsc#PED-529).

x86/bugs: Reenable retbleed=off While for older kernels the return
 thunks are statically built in and cannot be dynamically patched out,
 retbleed=off should still be possible to do so that the mitigation can
 still be disabled on Intel who do not use the return thunks but IBRS.");
