CVE-2019-14284: Linux Kernel

Medium severity, CVSS 6.2. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 5.2.3 (fixed in 5.2.3)
