CVE-2013-4515

Published: 12 November 2013

The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call.

From the Ubuntu security team

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for Beceem WIMAX chipset based devices. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory.
