From a192491ad58098f2c57d2d1efe721ea0634dc0aa Mon Sep 17 00:00:00 2001 From: Eric Sesterhenn Date: Wed, 21 Jun 2006 16:40:24 +0200 Subject: [PATCH] [PATCH] Array overrun in drivers/net/wireless/wavelan.c hi, this is another array overrun spotted by coverity (#id 507) we should check the index against array size before using it. Not sure why the driver doesnt use ARRAY_SIZE instead of its own macro.
