The record
IBM PowerVM Hypervisor Platform KeyStore (PKS) and virtual TPM FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 use persistent storage key seeds that result in an AES key with reduced strength. An attacker with access to the service processor or HMC could exploit this weakness to derive the encryption key and access the data.
