   An update that solves 7 vulnerabilities and has 7 fixes is
   now available.

Description:


   The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various
   security and bugfixes.

   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).
