IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the partition resource dump interface. An attacker with authenticated administrator-level access to the HMC or service processor can obtain a limited snapshot of partition processor state. Successful exploitation results in a confidentiality impact to the managed system.
