| Sažetak |
IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the FSP can send a specially crafted mailbox message to read or modify arbitrary regions of Hostboot memory, compromising the host firmware boot stack and the hypervisor subsequently loaded by it. Successful exploitation results in a confidentiality, integrity, and availability impact to the managed system. |
