    * kernel: a malicious USB device in the drivers/input/ff-memless.c leads to use-after-free     (CVE-2019-19524)

    * kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c (CVE-2020-9383)

    * kernel: null pointer dereference in dlpar_parse_cc_property in arch/powerrc/platforms/pseries/dlpar.c     causing denial of service (CVE-2019-12614)
