  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2019-3819: A flaw was fixed in the function hid_debug_events_read()
 in drivers/hid/hid-debug.c file which may have enter an infinite loop
 with certain parameters passed from a userspace. A local privileged user
 ('root') could have caused a system lock up and a denial of service
 (bnc#1123161).

CVE-2019-15118: Fixed kernel stack exhaustion in check_input_term in
 sound/usb/mixer.c via mishandled recursion (bnc#1145922).

CVE-2019-15117: Fixed out-of-bounds memory access in
 parse_audio_mixer_unit in sound/usb/mixer.c via mishandled short
 descriptor (bnc#1145920).

CVE-2019-14284: The drivers/block/floppy.c allowed a denial of service
 by setup_format_params division-by-zero. Two consecutive ioctls can
 trigger the bug: the first one should set the drive geometry with .sect
 and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy
 format operation should be called. It can be triggered by an
 unprivileged local user even when a floppy disk has not been inserted.
 NOTE: QEMU creates the floppy device by default (bsc#1143189).

CVE-2019-14283: The function set_geometry in drivers/block/floppy.c did
 not validate the sect and head fields, as demonstrated by an integer
 overflow and out-of-bounds read. It can be triggered by an unprivileged
 local user when a floppy disk has been inserted. NOTE: QEMU creates the
 floppy device by default (bsc#1143191).

CVE-2019-13631: In parse_hid_report_descriptor in
 drivers/input/tablet/gtco.c, a malicious USB device can send an HID
 report that triggers an out-of-bounds write during generation of
 debugging messages (bsc#1142023).

CVE-2019-11810: A NULL pointer dereference can occur when
 megasas_create_frame_pool() fails in megasas_alloc_cmds() in
 drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of
 Service, related to a use-after-free (bsc#1134399).

CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).

CVE-2019-10207: Check for missing tty operations in bluetooth/hci_uart
 (bsc#1142857).

CVE-2018-20856: Fixed a use-after-free issue in block/blk-core.c, where
 certain error case are mishandled (bnc#1143048).

CVE-2018-20855: An issue was discovered in create_qp_common in
 drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never
 initialized, resulting in a leak of stack memory to userspace
 (bsc#1143045).

CVE-2017-18551: An issue was discovered in drivers/i2c/i2c-core-smbus.c
 in the Linux kernel There was an out of bounds write in the function
 i2c_smbus_xfer_emulated (bnc#1146163).


The following non-security bugs were fixed:
bcache: add reclaimed_journal_buckets to struct cache_set (bsc#1140652,
 bsc#1144288).

bcache: fix race in btree_flush_write() (bsc#1140652, bsc#1144288).

bcache: fix stack corruption by PRECEDING_KEY() ... [Please see the references for more information on the vulnerabilities]");
