IBM Power Systems Firmware FW1060.00 through FW1060.81 is affected by a vulnerability in host firmware configuration parsing. An attacker with authenticated service-level access to the FSP can write specially crafted configuration data to cause memory corruption in the host firmware boot stage during system IPL, 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.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
