CVE-2021-20505: Medium severity IBM PowerVM Hypervisor vulnerability
The PowerVM Logical Partition Mobility(LPM) (PowerVM Hypervisor FW920, FW930, FW940, and FW950) encryption key exchange protocol can be compromised. If an attacker has the ability to capture encrypted LPM network traffic and is able to gain service access to the FSP they can use this information to perform a series of PowerVM service procedures to decrypt the captured migration traffic IBM X-Force ID: 198232
