CVE-2019-14283: Linux Kernel

Medium severity, CVSS 6.8. EPSS: 0.7% chance of exploitation in the next 30 days.

In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default.

Affected products

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