Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in the host firmware. An attacker with service access to the service processor can supply a carefully crafted command that could leak the contents of hardware registers that should be inaccessible to the service processor. Successful exploitation could result in limited confidentiality or availability impacts to the affected host system.

The CVE record on cve.org NVD's entry
The CVE record is authoritative. Products marked “from the name” were identified from the CNA's free-text names, not a CPE, and are matched less certainly. This product uses the NVD API but is not endorsed or certified by the NVD.
