The following security bugs were fixed:

CVE-2022-21127: Fixed a stale MMIO data transient which can be exploited
 to speculatively/transiently disclose information via spectre like
 attacks. (bsc#1199650)

CVE-2022-21123: Fixed a stale MMIO data transient which can be exploited
 to speculatively/transiently disclose information via spectre like
 attacks. (bsc#1199650)

CVE-2022-21125: Fixed a stale MMIO data transient which can be exploited
 to speculatively/transiently disclose information via spectre like
 attacks. (bsc#1199650)

CVE-2022-21180: Fixed a stale MMIO data transient which can be exploited
 to speculatively/transiently disclose information via spectre like
 attacks. (bsc#1199650)

CVE-2022-21166: Fixed a stale MMIO data transient which can be exploited
 to speculatively/transiently disclose information via spectre like
 attacks. (bsc#1199650)

CVE-2022-1975: Fixed a bug that allows an attacker to crash the linux
 kernel by simulating nfc device from user-space. (bsc#1200143)

CVE-2022-1974: Fixed an use-after-free that could causes kernel crash by
 simulating an nfc device from user-space. (bsc#1200144)

CVE-2022-1966: Fixed an use-after-free bug in the netfilter subsystem.
 This flaw allowed a local attacker with user access to cause a privilege
 escalation issue. (bnc#1200015)

CVE-2019-19377: Fixed an user-after-free that could be triggered when an
 attacker mounts a crafted btrfs filesystem image. (bnc#1158266)

CVE-2022-1729: Fixed a sys_perf_event_open() race condition against self
 (bsc#1199507).

CVE-2022-1184: Fixed an use-after-free and memory errors in ext4 when
 mounting and operating on a corrupted image. (bsc#1198577)

CVE-2022-21499: Reinforce the kernel lockdown feature, until now it's
 been trivial to break out of it with kgdb or kdb. (bsc#1199426)

CVE-2022-1652: Fixed a statically allocated error counter inside the
 floppy kernel module (bsc#1199063).

CVE-2022-1734: Fixed a r/w use-after-free when non synchronized between
 cleanup routine and firmware download routine. (bnc#1199605)

CVE-2021-39711: In bpf_prog_test_run_skb of test_run.c, there is a
 possible out of bounds read due to Incorrect Size Value. This could lead
 to local information disclosure with System execution privileges needed.
 User interaction is not needed for exploitation (bnc#1197219).

CVE-2022-30594: Fixed restriction bypass on setting the
 PT_SUSPEND_SECCOMP flag (bnc#1199505).

CVE-2021-33061: Fixed insufficient control flow management for the
 Intel(R) 82599 Ethernet Controllers and Adapters that may have allowed
 an authenticated user to potentially enable denial of service via local
 access (bnc#1196426).

The following non-security bugs were fixed:

ACPI: property: Release subnode properties with data nodes (git-fixes).

ARM: 9110/1: oabi-compat: fix oabi epoll sparse warning (bsc#1129770)

arm64: set ... [Please see the references for more information on the vulnerabilities]");
