Hi
Now I found that rpm file was replaced and the problem(cpio error) was fixed.

<MD5/SHA256 of old rpm>
#md5sum kernel-default-4.12.14-95.6.1.x86_64.rpm
6a0f642a4ec8b49d614fec6433e21805
# sha256sum kernel-default-4.12.14-95.6.1.x86_64.rpm
f31920f99db99018e23fd6807897566018a84ddc0437ff0fca 6df3f2aeee830c

<MD5/SHA256 of new rpm>
# md5sum kernel-default-4.12.14-95.6.1.x86_64.rpm
099ebd19b7170b1da6c323b2bbb6980d
# sha256sum kernel-default-4.12.14-95.6.1.x86_64.rpm
5d6e53aa7e2ca667534f1b51b8bc47b686e4d094205d634ca7 6780006b539450

Thany you all for your help!
