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.

[MEDIUM] Linux kernel regression
Title: Linux kernel regression
Summary: USN 4115-1 introduced a regression in the Linux kernel.
USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu
18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update,
a regression was introduced that caused a kernel crash when handling
fragmented packets in some situations. This update addresses the issue.
We apologize for the inconvenience.

It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default.
A vulnerability was found in the Linux kernel’s floppy disk driver implementation. A local attacker with access to the floppy device could call set_geometry in drivers/block/floppy.c, which does not validate the sect and head fields, causing an integer overflow and out-of-bounds read.

CVE-2019-14283 kernel: integer overflow and OOB read in drivers/block/floppy.c
A vulnerability was found in the Linux kernels floppy disk driver implementation. A local user with permissions to access the floppy device could call set_geometry in drivers/block/floppy.c which does not validate the sect and head fields causing an integer overflow and out-of-bounds read. This may crash the system or allow an attacker to gather information allowing for successful subsequent attacks.
Systems using QEMU will likely have the virtual floppy disk controller (FDC) enabled by default, Linux guests using this configuration will auto-load the floppy kernel module and likely be affected.
