In this paper, the Chinese block cipher algorithm SM4 is evaluated as a linear cryptanalysis method. As a result of the analysis, it was found that 2^126.4 plaintext and ciphertext pairs and 2^121.7 time complexity are required for 23 rounds of the SM4 algorithm for linear cryptanalysis. And to implement the round 23 attack by the multidimensional linear cryptanalysis required N = 2^122.3 plaintext and ciphertext pairs. The time complexity is equivalent to 2^122.5.
