CVE-2019-14284 Denial of service in n/a

What is CVE-2019-14284?

CVE-2019-14284 is a medium-severity denial of service vulnerability in Linux kernel, published on 26 Jul 2019. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-369
