kernel: integer overflow and OOB read in drivers/block/floppy.c

A vulnerability was found in the Linux kernel’s floppy disk driver implementation. A local attacker with access to the floppy device could call setgeometry 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 ma...

CVE-2019-14284

A vulnerability was found in the Linux kernel’s floppy disk driver implementation. A local attacker with access to the floppy disk device file /dev/fd0 through to /dev/fdN can create a situation that causes the kernel to divide by zero. This requires two consecutive ioctl calls to be issued. The...

CVE-2019-14283

In the Linux kernel before 5.2.3, setgeometry 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...

CVE-2019-14284

In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setupformatparams 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 FSECTPERTRACK be zero. Next, the floppy format...
