From 2132deff694765bc2e6c7ac84c6b30dab0775256 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 10 Mar 2010 07:57:03 -0300 Subject: [PATCH] V4L/DVB: omap24xxcam: potential buffer overflow The previous loop goes until last == VIDEO_MAX_FRAME, so this could potentially go one past the end of the loop.
