"The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit
a race condition in the Instruction Fetch Unit of the Intel CPU to
cause a Machine Exception during Page Size Change, causing the CPU
core to be non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size
changes in executable pages by splitting / merging huge pages into
small pages as needed. More information can be found on
https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-11135:
Aborting an asynchronous TSX operation on Intel CPUs with
Transactional Memory support could be used to facilitate sidechannel
information leaks out of microarchitectural buffers, similar to the
previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX
operation altogether (requiring CPU Microcode updates on older
systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at
https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233:
drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return
value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the
user space. (bsc#1144903).

CVE-2019-16232: Fix a potential NULL pointer dereference in the
Marwell libertas driver (bsc#1150465).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not
enforce CAP_NET_RAW, which meant that unprivileged users could create
a raw socket (bnc#1152782).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW,
which meant that unprivileged users could create a raw socket
(bsc#1152788).

CVE-2019-16413: The 9p filesystem did not protect i_size_write()
properly, which caused an i_size_read() infinite loop and denial of
service on SMP systems (bnc#1151347).

CVE-2019-15902: A backporting issue was discovered that re-introduced
the Spectre vulnerability it had aimed to eliminate. This occurred
because the backport process depends on cherry picking specific
commits, and because two (correctly ordered) code lines were swapped
(bnc#1149376).

CVE-2019-15291: Fixed a NULL pointer dereference issue that could be
caused by a malicious USB device (bnc#11465).

CVE-2019-15807: Fixed a memory leak in the SCSI module that could be
abused to cause denial of service (bnc#1148938).

CVE-2019-14821: An out-of-bounds access issue was fixed in the
kernel's KVM hypervisor. An unprivileged host user or process with
access to '/dev/kvm' device could use this flaw to crash the host
kernel, resulting in a denial of service or potentially escalating
privileges on the system (bnc#1151350).

CVE-2019-15505: An out-of-bounds issue had been fixed that could be
caused by crafted USB device traffic (bnc#1147122).

CVE-2017-18595: A double free in allocate_trace_buffer was fixed
(bnc#1149555).

CVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost
functionality that translates virtqueue buffers to IOVs. A privileged
guest user able to pass descriptors with invalid length to the host
could use this flaw to increase their privileges on the host
(bnc#1150112).

CVE-2019-15216: A NULL pointer dereference was fixed that could be
malicious USB device (bnc#1146361).

CVE-2019-9456: An out-of-bounds write in the USB monitor driver has
been fixed. This issue could lead to local escalation of privilege
with System execution privileges needed. (bnc#1150025).

CVE-2019-15926: An out-of-bounds access was fixed in the
drivers/net/wireless/ath/ath6kl module. (bnc#1149527).

CVE-2019-15927: An out-of-bounds access was fixed in the
sound/usb/mixer module (bnc#1149522).

CVE-2019-15219: A NULL pointer dereference was fixed that could be
abused by a malicious USB device (bnc#1146524).

CVE-2019-15220: A use-after-free issue was fixed that could be caused
by a malicious USB device (bnc#1146526).

CVE-2019-15221: A NULL pointer dereference was fixed that could be
caused by a malicious USB device (bnc#1146529).

CVE-2019-14814: A heap-based buffer overflow was fixed in the marvell
wifi chip driver. That issue allowed local users to cause a denial of
service (system crash) or possibly execute arbitrary code
(bnc#1146512).

CVE-2019-14815: A missing length check while parsing WMM IEs was fixed
(bsc#1146512, bsc#1146514, bsc#1146516).

CVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip
driver was fixed. Local users would have abused this issue to cause a
denial of service (system crash) or possibly execute arbitrary code
(bnc#1146516).

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific
socket option, an attacker could control a pointer in kernel land and
cause an inet_csk_listen_stop general protection fault, or potentially
execute arbitrary code under certain circumstances. The issue can be
triggered as root (e.g., inside a default LXC container or with the
CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit
sufficiently low encryption key length and did not prevent an attacker
from influencing the key length negotiation. This allowed practical
brute-force attacks (aka 'KNOB') that could decrypt traffic and inject
arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath
was fixed (bnc#1146378).

CVE-2019-15290: A NULL pointer dereference in
ath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).

CVE-2019-15212: A double-free issue was fixed in drivers/usb driver
(bnc#1146391).

CVE-2016-10906: A use-after-free issue was fixed in
drivers/net/ethernet/arc (bnc#1146584).

CVE-2019-15217: A a NULL pointer dereference issue caused by a
malicious USB device was fixed in the drivers/media/usb/zr364xx driver
(bnc#1146519).

CVE-2019-15218: A NULL pointer dereference caused by a malicious USB
device was fixed in the drivers/media/usb/siano driver (bnc#1146413).

CVE-2019-15215: A use-after-free issue caused by a malicious USB
device was fixed in the drivers/media/usb/cpia2 driver (bnc#1146425).

CVE-2018-20976: A use-after-free issue was fixed in the fs/xfs driver
(bnc#1146285).

CVE-2017-18551: An out-of-bounds write was fixed in the drivers/i2c
driver (bnc#1146163).

CVE-2019-10207: Add checks for missing tty operations to prevent
unprivileged user to execute 0x0 address (bsc#1142857 bsc#1123959)

CVE-2019-15118: ALSA: usb-audio: Fix a stack-based buffer overflow bug
in check_input_term leading to kernel stack exhaustion (bsc#1145922).
