   An update that solves 7 vulnerabilities and has 13 fixes is
   now available.

Description:

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

   The following security bugs were fixed:

   - CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
   - 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-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-2019-11810: 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-2019-13648: In the Linux kernel on the powerpc platform, when
     hardware transactional memory is disabled, a local user can cause a
     denial of service (TM Bad Thing exception and system crash) via a
     sigreturn() system call that sends a crafted signal frame. This affects
     arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c
     (bnc#1142254).
   - 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).

   The following non-security bugs were fixed:

   - bcache: Revert "bcache: fix high CPU occupancy during journal"
     (bsc#1140652, bsc#1144288).
   - bcache: Revert "bcache: free heap cache_set->flush_btree in
     bch_journal_free" (bsc#1140652, bsc#1144288).
   - 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).
   - mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing
     (bsc#1142098).
   - powerpc/watchpoint: Restore NV GPRs while returning from exception
     (bsc#1140945, bsc#1141401, bsc#1141402, bsc#1141452, bsc#1141453,
     bsc#1141454).
   - xen-netfront: use napi_complete() correctly to prevent Rx stalling
     (bsc#1138744).
