Same could be the case for fips_mct_shake_test also.

Good catch, probably the same could happen with shake.
I currently don’t have a way to test shake but I'm happy to make the
change as part of this patch if you can test?

Did you find any segfault and so got to know the problem ? If so, what was the
command you executed ?.

Thanks,
Gowrishankar

Running fips sample app with aesni_mb and SHA ACVP test vector files. Also occurs with QAT. 
./dpdk-fips_validation --vdev=crypto_aesni_mb -- --req-file $FIPS_DIR/$alg/req --rsp-file $FIPS_DIR/$alg/resp_aesni_mb --path-is-folder

Output shows invalid memory bug.

SHAKE is not supported by these hence I did not catch it.
