Summary
IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in the interface between the BMC/FSP and the host system. An attacker with service account or root access to the BMC/FSP can execute arbitrary code on the host system, giving full control over the host system and all hosted partitions, resulting in a confidentiality, integrity, and availability impact.
