After fips_mct_sha_test() and fips_mct_shake_test() complete, vec.pt.val is freed but left as a non-NULL dangling pointer. Since vec is a file-scope global, the next SHA algorithm's AFT test calls parse_uint8_hex_str(&vec.pt), which checks val->val and calls rte_free() on the stale pointer, producing:
EAL: Error: Invalid memory Fix by setting vec.pt.val to NULL after rte_free() at the end of both MCT functions so the subsequent rte_free() guard in parse_uint8_hex_str() skips the already-freed pointer.
