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).
