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).
