Revision a5cd335165e31db9dbab636fd29895d41da55dd2 authored by Xi Wang on 23 November 2011, 06:12:01 UTC, committed by Dave Airlie on 23 November 2011, 08:59:28 UTC
There is a potential integer overflow in drm_mode_dirtyfb_ioctl() if userspace passes in a large num_clips. The call to kmalloc would allocate a small buffer, and the call to fb->funcs->dirty may result in a memory corruption.
