Vulnerability from github – Published: 2026-08-19 21:30 – Updated: 2026-08-19 21:30

Details

IBM Power Systems Firmware FW1120.00, and FW1110.00 through FW1110.30 is affected by a vulnerability in the interface between the BMC and the host system. An attacker with service access to the BMC can send a specially crafted command, allowing arbitrary code to be executed on the host system, giving full control over the host system and all hosted partitions, resulting in a confidentiality, integrity, and availability impact.

Severity

8.2 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
