"The SUSE Linux Enterprise 12 SP 3 LTSS kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed :

CVE-2019-14895: A heap-based buffer overflow was discovered in the
Linux kernel in Marvell WiFi chip driver. The flaw could occur when
the station attempts a connection negotiation during the handling of
the remote devices country settings. This could have allowed the
remote device to cause a denial of service (system crash) or possibly
execute arbitrary code (bnc#1157158).

CVE-2019-18660: The Linux kernel on powerpc allowed Information
Exposure because the Spectre-RSB mitigation is not in place for all
applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and
arch/powerpc/kernel/security.c (bnc#1157038).

CVE-2019-18683: An issue was discovered in
drivers/media/platform/vivid in the Linux kernel. It is exploitable
for privilege escalation on some Linux distributions where local users
have /dev/video0 access, but only if the driver happens to be loaded.
There are multiple race conditions during streaming stopping in this
driver (part of the V4L2 subsystem). These issues are caused by wrong
mutex locking in vivid_stop_generating_vid_cap(),
vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the
corresponding kthreads. At least one of these race conditions leads to
a use-after-free (bnc#1155897).

CVE-2019-19062: A memory leak in the crypto_report() function in
crypto/crypto_user_base.c in the Linux kernel allowed attackers to
cause a denial of service (memory consumption) by triggering
crypto_report_alg() failures (bnc#1157333).

CVE-2019-19065: A memory leak in the sdma_init() function in
drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel allowed
attackers to cause a denial of service (memory consumption) by
triggering rhashtable_init() failures (bnc#1157191).

CVE-2019-19052: A memory leak in the gs_can_open() function in
drivers/net/can/usb/gs_usb.c in the Linux kernel allowed attackers to
cause a denial of service (memory consumption) by triggering
usb_submit_urb() failures (bnc#1157324).

CVE-2019-19074: A memory leak in the ath9k_wmi_cmd() function in
drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel allowed
attackers to cause a denial of service (memory consumption)
(bnc#1157143).

CVE-2019-19073: Memory leaks in
drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel allowed
attackers to cause a denial of service (memory consumption) by
triggering wait_for_completion_timeout() failures. This affects the
htc_config_pipe_credits() function, the htc_setup_complete() function,
and the htc_connect_service() function (bnc#1157070).

CVE-2019-16231: drivers/net/fjes/fjes_main.c in the Linux kernel
5.2.14 did not check the alloc_workqueue return value, leading to a
NULL pointer dereference (bnc#1150466).

CVE-2019-18805: An issue was discovered in net/ipv4/sysctl_net_ipv4.c
in the Linux kernel There was a net/ipv4/tcp_input.c signed integer
overflow in tcp_ack_update_rtt() when userspace writes a very large
integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of
service or possibly unspecified other impact (bnc#1156187).

CVE-2019-18680: An issue was discovered in the Linux kernel. There was
a NULL pointer dereference in rds_tcp_kill_sock() in net/rds/tcp.c
that will cause denial of service (bnc#1155898).

CVE-2019-15213: An use-after-free was fixed caused by malicious USB
device in drivers/media/usb/dvb-usb/dvb-usb-init.c (bsc#1146544).

CVE-2019-19536: An uninitialized Kernel memory can leak to USB devices
in drivers/net/can/usb/peak_usb/pcan_usb_pro.c (bsc#1158394).

CVE-2019-19534: An uninitialized Kernel memory can leak to USB devices
in drivers/net/can/usb/peak_usb/pcan_usb_core.c (bsc#1158398).

CVE-2019-19530: An use-after-free bug that can be caused by a
malicious USB device in the drivers/usb/class/cdc-acm.c driver
(bsc#1158410).

CVE-2019-19524: An use-after-free bug that can be caused by a
malicious USB device in the drivers/input/ff-memless.c driver
(bsc#1158413).

CVE-2019-19525: An use-after-free bug that can be caused by a
malicious USB device in the drivers/net/ieee802154/atusb.c driver
(bsc#1158417).

CVE-2019-19531: An use-after-free in yurex_delete may lead to denial
of service (bsc#1158445).

CVE-2019-19523: An use-after-free on disconnect in USB adutux
(bsc#1158823).

CVE-2019-19532: An out-of-bounds write bugs that can be caused by a
malicious USB device in the Linux kernel HID drivers (bsc#1158824).

CVE-2019-19332: An out-of-bounds memory write via
kvm_dev_ioctl_get_cpuid (bsc#1158827).

CVE-2019-19533: An info-leak bug that can be caused by a malicious USB
device in the drivers/media/usb/ttusb-dec/ttusb_dec.c driver
(bsc#1158834).

CVE-2019-19527: An use-after-free bug that can be caused by a
malicious USB device in the drivers/hid/usbhid/hiddev.c driver
(bsc#1158900).

CVE-2019-19535: An info-leak bug that can be caused by a malicious USB
device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver
(bsc#1158903).

CVE-2019-19537: Two races in the USB character device registration and
deregistration routines (bsc#1158904).

CVE-2019-19338: An incomplete fix for Transaction Asynchronous Abort
(TAA) (bsc#1158954).

The update package also includes non-security fixes. See advisory for
details.
