However,\nvfe-\u003eline[] array is defined with VFE_LINE_NUM_MAX(4):\n\n    struct vfe_line line[VFE_LINE_NUM_MAX];\n\nWhen index is 4, 5, 6, the access to vfe-\u003eline[line_id] exceeds\nthe array bounds and resulting in out-of-bounds memory access.\n\nFix this by using separate loops for output lines and write masters.",
