   An update that solves 12 vulnerabilities and has 19 fixes
   is now available.

Description:

    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() (bsc#1130972,
     bsc#1144257).
   - bcache: only set BCACHE_DEV_WB_RUNNING when cached device attached
     (bsc#1130972, bsc#1144273).
   - bcache: performance improvement for btree_flush_write() (bsc#1140652,
     bsc#1144288).
   - bcache: remove retry_flush_write from struct cache_set (bsc#1140652,
     bsc#1144288).
   - btrfs: improve delayed refs iterations (bsc#1076033, bsc#1107256).
   - i40e: add functions to control default VSI (bsc#1141628).
   - i40e: set default VSI without a reset (bsc#1141628).
   - mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing
     (bsc#1142098).
   - nfs: Fix the inode request accounting when pages have subrequests
     (bsc#1140012).
   - powerpc/watchpoint: Restore NV GPRs while returning from exception
   (bsc#1140945,bsc#1141401,bsc#1141402,bsc#1141452,bsc#1141453,bsc#1141454).

   - qib/hfi1: Fix MR reference count leak on write with immediate
     (bsc#1045640).
   - sched/fair: Do not free p->numa_faults with concurrent readers
     (bsc#1144920).
   - sched/fair: Use RCU accessors consistently for ->numa_group
     (bsc#1144920).
   - x86, mm: fix fast GUP with hyper-based TLB flushing (VM Functionality,
     bsc#1140903).
   - xen: let alloc_xenballooned_pages() fail if not enough memory free
     (XSA-300).
