  The following security bugs were fixed:

  - CVE-2019-1125: Fix Spectre V1 variant memory disclosure by speculation
  over the SWAPGS instruction (bsc#1139358).

  - CVE-2019-10207: A NULL pointer dereference was possible in the bluetooth
  stack, which could lead to crashes. (bnc#1123959 bnc#1142857).

  - CVE-2018-20855: 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 (bnc#1143045).

  - CVE-2019-14284: 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. (bnc#1143189).

  - CVE-2019-14283: 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. (bnc#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 (bnc#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 bnc#1142265).

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

  The following non-security bugs were fixed:

  - 9p: acl: fix uninitialized iattr access (bsc#1051510).

  - 9p: p9dirent_read: check network-provided name length (bsc#1051510).

  - 9p: pass the correct prototype to read_cache_page (bsc#1051510).

  - 9p/rdma: do not disconnect on down_interruptible EAGAIN (bsc#1051510).

  - 9p/rdma: remove useless check in cm_event_handler (bsc#1051510).

  - 9p/virtio: Add cleanup path in p9_virtio_init (bsc#1051510).

  - 9p/x ...
