Thanks.
The out-of-bound access seems to be in vgacon_scroll() and thus in vgacon code.
Unfortunately, most people in CC are printk-guys. They were mentioned by ./scripts/get_maintainer.pl -f drivers/video/console/vgacon.c just because the very last comment (tree wide pr_warning() clean up).
Bartolomej seems to be the only relevant name.
Bartolomej,
are you going to look at it? Or should we add more people or some list (dri-devel@lists.freedesktop.org or linux-fbdev@vger.kernel.org) into CC?
Thanks, Petr
