Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slub overflow in ksmbd_decode_ntlmssp_auth_blob()
If authblob->SessionKey.Length is bigger than session key
size(CIFS_KEY_SIZE), slub overflow can happen in key exchange codes.
cifs_arc4_crypt copy to session key array from SessionKey from client.
