The struct dcd_v1_t is initialized to MAX_HW_CFG_SIZE_V1 (60) structs 'dcd_type_addr_data_t', so the indexes to use on its elements are [0,59]. But on line 478, the variable 'length' can take on the value 60, which applies to array overflow: cd_v1->addr_data[length].type Thus, it is necessary to tighten the check on the 'size' variable on line 463.
