The following security bugs were fixed:

CVE-2022-36946: Fixed an incorrect packet trucation operation which
 could lead to denial of service (bnc#1201940).

CVE-2022-20166: Fixed several possible memory safety issues due to
 unsafe operations (bsc#1200598).

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

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

CVE-2021-33656: Fixed memory out of bounds write related to ioctl cmd
 PIO_FONT (bnc#1201636).

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

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

The following non-security bugs were fixed:

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

qla2xxx: drop patch which prevented nvme port discovery (bsc#1200651
 bsc#1200644 bsc#1201954 bsc#1201958).

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

nfs: avoid NULL pointer dereference when there is unflushed data
 (bsc#1201196).

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

lkdtm: Disable return thunks in rodata.c (bsc#1114648).

powerpc/64: Move paca allocation later in boot (bsc#1190812).

powerpc/fadump: fix PT_LOAD segment for boot memory area (bsc#1103269
 ltc#169948).

powerpc/fadump: make crash memory ranges array allocation generic
 (bsc#1103269 ltc#169948).

powerpc: Set crashkernel offset to mid of RMA region (bsc#1190812).

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 (bsc#1195775)

rpm/kernel-obs-build.spec.in: use default dracut modules (bsc#1195926,
 bsc#1198484) Let's iron out the reduced initrd optimisation in
 Tumbleweed. Build full blown dracut initrd with systemd for SLE15 SP4.

scsi: qla2xxx: Add a new v2 dport diagnostic feature (bsc#1201958).

scsi: qla2xxx: Add debug prints in the device remove path (bsc#1201958).
