Security update for the Linux Kernel (important)

An update that solves four vulnerabilities and has 37 fixes
is now available.

Description:

The openSUSE Leap 15.1 kernel was updated to receive various security and
bugfixes.

The following security bugs were fixed:

• CVE-2020-8647: There was a use-after-free vulnerability in the
  vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929 1164078).
• CVE-2020-8649: There was a use-after-free vulnerability in the
  vgacon_invert_region function in drivers/video/console/vgacon.c
  (bnc#1162929 1162931).
• CVE-2020-9383: An issue was discovered in the set_fdc in
  drivers/block/floppy.c that lead to a wait_til_ready out-of-bounds read
  because the FDC index is not checked for errors before assigning it, aka
  CID-2e90ca68b0d2 (bnc#1165111).
• CVE-2019-19768: There was a use-after-free (read) in the __blk_add_trace
  function in kernel/trace/blktrace.c (which is used to fill out a
  blk_io_trace structure and place it in a per-cpu sub-buffer)
  (bnc#1159285).
