Hello Takahiro, when trying to execute command
ut lib lib_rsa_verify_valid on qemu_arm_defconfig with CONFIG_UNIT_TEST=y and CONFIG_RSA_VERIFY_WITH_PKEY=y it crashes in free((void *)prop->modulus) called from rsa_free_key_prop() called from rsa_verify_key() called from rsa_verify_with_pkey(). Without CONFIG_RSA_VERIFY_WITH_PKEY=y the problem does not occur. On qemu_arm64_defconfig the problem does not occur. Could you, please, have a look. Best regards Heinrich
