CVE-2014-1738

Published: 11 May 2014

The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device.

From the Ubuntu security team

Matthew Daley reported an information leak in the floppy disk driver of the Linux kernel. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from kernel memory.
