The following security bugs were fixed:

CVE-2020-16119: Fixed a use-after-free vulnerability exploitable by a
 local attacker due to reuse of a DCCP socket. (bnc#1177471)

CVE-2022-20008: Fixed a bug which allowed to read kernel heap memory due
 to uninitialized data. This could lead to local information disclosure
 if reading from an SD card that triggers errors, with no additional
 execution privileges needed. (bnc#1199564)

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-2022-2586: Fixed a use-after-free which can be triggered when a nft
 table is deleted (bnc#1202095).

CVE-2022-32296: Fixed a bug which allowed TCP servers 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-2022-41222: Fixed a use-after-free via a stale TLB because an rmap
 lock is not held during a PUD move (bnc#1203622).

CVE-2022-41674: Fixed a DoS issue where kernel can crash on the
 reception of specific WiFi Frames (bsc#1203770).

CVE-2022-41848: Fixed a race condition and resultant use-after-free if a
 physically proximate attacker removes a PCMCIA device while calling
 ioctl (bnc#1203987).

CVE-2022-41849: Fixed a race condition and resultant use-after-free if a
 physically proximate attacker removes a USB device while calling open
 (bnc#1203992).

CVE-2022-42719: Fixed remote code execution with wlan frames when
 parsing a multi-BSSID element (bsc#1204051).

CVE-2022-42720: Fixed remote code execution due to refcounting bugs
 (bsc#1204059).

CVE-2022-42721: Fixed remote code execution due list corruption in the
 wlan stack (bsc#1204060).

The following non-security bugs were fixed:

net: mana: Add support of XDP_REDIRECT action (bsc#1201310, jsc#PED-529).

net: mana: Add the Linux MANA PF driver (bsc#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 work so that it can be disabled.");
