Summary
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.

Dos ioctls consecutivos pueden desencadenar el error: el primero debe establecer la geometr\u00eda de la unidad con valores .sect y .rate que hacen que F_SECT_PER_TRACK sea cero. A continuaci\u00f3n, se debe llamar a la operaci\u00f3n de formato de disquete. Puede ser activado por un usuario local sin privilegios incluso cuando no se ha insertado un disquete. NOTA: QEMU crea el dispositivo de disquete de por defecto."
