Description

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.
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. This flaw may crash the system or allow an attacker to gather information causing subsequent successful attacks.
