CVE-2019-14284

In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setupformatparams 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 FSECTPER_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.
