  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-2021-33655: 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:

  - 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: 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).

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

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

  - 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 (bsc#1195775)

  - rpm/kernel-obs-build.spec.in: use default dracut modules (bsc#1195926,
       bsc#1198484)

  - x86/entry: Remove skip_r11rcx (bsc#1201644).
