An update that solves 8 vulnerabilities and has 6 fixes is
now available.
Description:
The SUSE Linux Enterprise 15 LTSS 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-2021-26341: Some AMD CPUs may transiently execute beyond
unconditional direct branches, which may potentially result in data
leakage (bsc#1201050).
- 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:
- Add missing recommends of kernel-install-tools to kernel-source-vanilla
(bsc#1200442)
- 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: fix potential use-after-free in cifs_echo_request() (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).
- kernel-binary.spec: Support radio selection for debuginfo. To disable
debuginfo on 5.18 kernel a radio selection needs to be switched to a
different selection. This requires disabling the currently active option
and selecting NONE as debuginfo type.
- kernel-binary.spec: check s390x vmlinux location As a side effect of
mainline commit edd4a8667355 ("s390/boot: get rid of startup archive"),
vmlinux on s390x moved from "compressed" subdirectory directly into
arch/s390/boot. As the specfile is shared among branches, check both
locations and let objcopy use one that exists.
- kvm: emulate: Fix SETcc emulation function offsets with SLS
(bsc#1201930).
- kvm: emulate: do not adjust size of fastop and setcc subroutines
(bsc#1201930).
- pahole 1.22 required for full BTF features. also recommend pahole for
kernel-source to make the kernel buildable with standard config
- 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).
Special Instructions and Notes:
Please reboot the system after installing this update.
Patch Instructions:
To install this SUSE Security Update use the SUSE recommended installation methods
like YaST online_update or "zypper patch".
Alternatively you can run the command listed for your product:
- SUSE Linux Enterprise Server for SAP 15:
zypper in -t patch SUSE-SLE-Product-SLES_SAP-15-2022-2723=1
