kernel: Information exposure in fd_locked_ioctl function in drivers/block/floppy.c

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location ...

Linux kernel input validation error vulnerability (CNVD-2019-38522)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An input validation error vulnerability exists in the 'setgeometry' function of the drivers/block/floppy.c file in versions of Linux kernel prior to 5.2.3. The...

Linux kernel integer overflow vulnerability (CNVD-2019-25055)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An integer overflow vulnerability exists in the 'setupformatparams' function in the drivers/block/floppy.c file in Linux kernel versions prior to 5.2.3. The...

DEBIAN-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...

Integer overflow

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...
