Is the same private key using k and k*2 respectively in two different signatures vulnerable? If yes How to calculate the key in this case

Here is an example, Both signatures are valid and the nonce of r2,s2,z2 is double the first signature's nonce, how do I calculate private key from these two signatures?

r1 = 0xdcf17de661e280dbf62e03ef1655d1baaabc301da9fc6b29a63e52e7780c115d
s1 = 0x20be91ddd5598e22fa43014172df5312275fbdb462a2e9855c7a7433138a4a9c
z1 = 0xbb1e00d2027efd3085b83de2a3602a8ea49e0c9d5b821cd6291d5feefd410303

r2 = 0x5baeea47c4d1759efc2b4a6a1948727648a7f9d0db6c77c09b0a26a0ae22d4ad
s2 = 0x4f08689cd10e8fd5e9be108d18e2ee582774dc409176643800284669d6e787eb
z2 = 0x0fa25a9a0712366012de680bed93f8c94ffa2c119464d1e59b0a03b1c115b54f
