Message-ID: <4730F168.4010203@tiscali.nl> Date: Tue, 06 Nov 2007 23:57:44 +0100 From: Roel Kluin <12o3l@...cali.nl> To: lkml <linux-kernel@...r.kernel.org> Subject: [PATCH] fix writing to unintended memory in eth16i_probe_port(); drivers/net/eth16i.c 14 is added as an offset to the array dummy_packet (64 unsigned chars) to serve as a destination address in a call to memset(). However, when added, it is automatically scaled by the size of dummy_packet, which is 64. This results in writing to unintended memory.
