Smatch reports two issues: drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_num' 3 <= 4 drivers/media/platform/sh_vou.c:670 vou_adjust_output() error: buffer overflow 'vou_scale_v_den' 3 <= 4 It seems that there's actually a bug here: the same var (idx) is used as an index for vertical and horizontal scaling arrays. However, there are 4 elements on the h arrays, and only 3 at the v ones. On the first loop, it may select index 4 for the horizontal array. In this case, if the second loop fails to select an index, the code would keep using 4 for the vertical array, with is past of the array sizes. The intent here seems to use index 0, if the scale is not found. So, use a separate var for the vertical index. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> |
