From f7a595e98c3140f1271957aa742a6b84407620d4 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Tue, 22 Sep 2009 16:47:38 -0700 Subject: [PATCH] drivers/video/console/newport_con.c: fix read outside array bounds It reads linetable[] before checking bounds of index, and ARRAY_SIZE is required because linetable[] are unsigned shorts.
