DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious, local users to disclose potentially sensitive
information.

The vulnerability is caused due to the "drm_ioctl()" function in
drivers/gpu/drm/drm_drv.c not properly cleaning kernel memory before
copying it to the userspace, which can be exploited to disclose
potentially sensitive information by sending specially crafted
IOCTLs.

Successful exploitation requires that the user has read and write
access to the DRI path (e.g. is part of the "video" group).

SOLUTION:
Fixed in the GIT repository of Dave Airlie.
