An update that solves four vulnerabilities and has 6 fixes
is now available.
Description:
The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- 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).
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.
- 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).
