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...
