The following security bugs were fixed:

CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c
 vulnerability in the Linux kernel (bnc#1198031).

CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c
 vulnerability in the Linux kernel (bnc#1198032).

CVE-2018-20784: Fixed a denial of service (infinite loop in
 update_blocked_averages) by mishandled leaf cfs_rq in
 kernel/sched/fair.c (bnc#1126703).

CVE-2018-7755: Fixed an issue in the fd_locked_ioctl function in
 drivers/block/floppy.c. The floppy driver will copy a kernel pointer to
 user memory in response to the FDGETPRM ioctl. An attacker can send the
 FDGETPRM ioctl and use the obtained kernel pointer to discover the
 location of kernel code and data and bypass kernel security protections
 such as KASLR (bnc#1084513).

CVE-2020-10769: Fixed a buffer over-read flaw in the IPsec Cryptographic
 algorithm's module. This flaw allowed a local attacker with user
 privileges to cause a denial of service. (bnc#1173265)

CVE-2021-28688: Fixed XSA-365 that includes initialization of pointers
 such that subsequent cleanup code wouldn't use uninitialized or stale
 values. This initialization went too far and may under certain
 conditions also overwrite pointers which are in need of cleaning up. The
 lack of cleanup would result in leaking persistent grants. The leak in
 turn would prevent fully cleaning up after a respective guest has died,
 leaving around zombie domains (bnc#1183646).

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

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