Vulnerability Type: +Info 
CWE ID: CWE-200
Summary: 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.
Commit Message: Staging: bcm: info leak in ioctl

The DevInfo.u32Reserved[] array isn't initialized so it leaks kernel
information to user space.
