Subject: [-next] [bug report] media/IR/imon: array overflow
Date: Tue, 4 May 2010 14:20:30 +0200	[thread overview]
Message-ID: <20100504122030.GX29093@bicker> (raw)

This is a Smatch thing.  I'm not sure what's intended.

drivers/media/IR/imon.c +1211 imon_panel_key_lookup(10) error: buffer overflow 'imon_panel_key_table' 21 <= 21
  1207          for (i = 0; i < ARRAY_SIZE(imon_panel_key_table); i++)
  1208                  if (imon_panel_key_table[i].hw_code == (code | 0xffee))
  1209                          break;

After the for loop i can be 0 to 21.

  1210
  1211          keycode = imon_panel_key_table[i % IMON_KEY_RELEASE_OFFSET].keycode;

IMON_KEY_RELEASE_OFFSET is 1000 so it doesn't affect anything.

regards,
dan carpenter
