PowerVM Hypervisor Vulnerability in Encryption Key Exchange Protocol

CVE-2021-20505

Summary

The encryption key exchange protocol within IBM's PowerVM Logical Partition Mobility (LPM) has been identified as vulnerable. An attacker capable of intercepting encrypted LPM network traffic, combined with unauthorized access to the Flexible Service Processor (FSP), can exploit this vulnerability. By capturing and analyzing the traffic, the attacker may carry out subsequent PowerVM service procedures to decrypt the sensitive migration traffic, potentially compromising sensitive data and system integrity.
