The following security bugs were fixed:

CVE-2020-36557: Fixed race condition between the VT_DISALLOCATE ioctl
 and closing/opening of ttys that could lead to a use-after-free
 (bnc#1201429).

CVE-2020-36558: Fixed race condition involving VT_RESIZEX that could
 lead to a NULL pointer dereference and general protection fault
 (bnc#1200910).

CVE-2021-26341: Some AMD CPUs may transiently execute beyond
 unconditional direct branches, which may potentially result in data
 leakage (bsc#1201050).

CVE-2021-33655: Fixed out of bounds write with ioctl FBIOPUT_VSCREENINFO
 (bnc#1201635).

CVE-2021-33656: Fixed out of bounds write with ioctl PIO_FONT
 (bnc#1201636).

CVE-2022-1462: Fixed an out-of-bounds read flaw in the TeleTYpe
 subsystem (bnc#1198829).

CVE-2022-20166: Fixed possible out of bounds write due to sprintf
 unsafety that could cause local escalation of privilege (bnc#1200598).

CVE-2022-36946: Fixed incorrect packet truncation in nfqnl_mangle() that
 could lead to remote DoS (bnc#1201940).

The following non-security bugs were fixed:

Add missing recommends of kernel-install-tools to kernel-source-vanilla
 (bsc#1200442)

cifs: On cifs_reconnect, resolve the hostname again (bsc#1201926).

cifs: Simplify reconnect code when dfs upcall is enabled (bsc#1201926).

cifs: To match file servers, make sure the server hostname matches
 (bsc#1201926).

cifs: fix memory leak of smb3_fs_context_dup::server_hostname
 (bsc#1201926).

cifs: fix potential use-after-free in cifs_echo_request() (bsc#1201926).

cifs: set a minimum of 120s for next dns resolution (bsc#1201926).

cifs: use the expiry output of dns_query to schedule next resolution
 (bsc#1201926).

kernel-binary.spec: Support radio selection for debuginfo. To disable
 debuginfo on 5.18 kernel a radio selection needs to be switched to a
 different selection. This requires disabling the currently active option
 and selecting NONE as debuginfo type.

kernel-binary.spec: check s390x vmlinux location As a side effect of
 mainline commit edd4a8667355 ('s390/boot: get rid of startup archive'),
 vmlinux on s390x moved from 'compressed' subdirectory directly into
 arch/s390/boot. As the specfile is shared among branches, check both
 locations and let objcopy use one that exists.

kvm: emulate: Fix SETcc emulation function offsets with SLS
 (bsc#1201930).

kvm: emulate: do not adjust size of fastop and setcc subroutines
 (bsc#1201930).

pahole 1.22 required for full BTF features. also recommend pahole for
 kernel-source to make the kernel buildable with standard config

rpm/*.spec.in: remove backtick usage

rpm/constraints.in: skip SLOW_DISK workers for kernel-source

rpm/kernel-obs-build.spec.in: Also depend on dracut-systemd (bsc#1195775)

rpm/kernel-obs-build.spec.in: add systemd-initrd and terminfo dracut
 module ... [Please see the references for more information on the vulnerabilities]");
