The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246 bytes of uninitialized stack memory, because the "reserved" member of the viafb_ioctl_info struct declared on the stack is not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: NDan Rosenberg <dan.j.rosenberg@gmail.com> Signed-off-by: NFlorian Tobias Schandinat <FlorianSchandinat@gmx.de>
