CVE-2019-14284

Priority
Description
In the Linux kernel before 5.2.3, drivers/block/floppy.c allows 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.
Ubuntu-Description
It was discovered that the floppy driver in the Linux kernel did not
properly validate ioctl() calls, leading to a division-by-zero. A local
attacker could use this to cause a denial of service (system crash).
