The following security bugs were fixed:

CVE-2022-20008: Fixed local information disclosure due to possibility to
 read kernel heap memory via mmc_blk_read_single of block.c (bnc#1199564).

CVE-2022-2503: Fixed a vulnerability that allowed root to bypass LoadPin
 and load untrusted and unverified kernel modules and firmware
 (bnc#1202677).

CVE-2022-32296: Fixed vulnerability where TCP servers were allowed to
 identify clients by observing what source ports are used (bnc#1200288).

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-2022-3303: 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-2022-41848: Fixed a race condition in
 drivers/char/pcmcia/synclink_cs.c mgslpc_ioctl and mgslpc_detach
 (bnc#1203987).

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.

mkspec: eliminate @NOSOURCE@ macro This should be alsways used with
 @SOURCES@, just include the content there.

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

net: mana: Add the Linux MANA PF driver (bnc#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.");
