From 233d84c46c2253d13e10b42d88c14748fbb67a98 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 20 Jan 2011 22:37:43 +0100 Subject: ALSA: Xonar, CS43xx: Don't overrun static array 'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of 8. So, this code in sound/pci/oxygen/xonar_cs43xx.c::dump_d1_registers() for (i = 2; i <= 8; ++i) snd_iprintf(buffer, " %02x", data->cs4398_regs[i]); will overrun the array when 'i == 8'. I guess that what's needed to fix it is the trivial patch below, but I must admit that I have no idea about this code, so I may very well be wrong. Additionally, I have no way to actually test this, so all I know is that the below compiles. Someone who actually knows this code should take a look before anything is comitted - consider the below (not much more than) a bug report.
