Attack-Flow Graph

Executive Summary

CVE-2026-16930 is a vulnerability in IBM Power Systems Firmware where an attacker with service account or root access to the BMC/FSP can execute arbitrary code on the host system. This gives full control over the host and all hosted partitions, leading to confidentiality, integrity, and availability impacts.

Detection Guidance

Detection requires checking the firmware version of IBM Power Systems. Compare your firmware against affected versions: FW1120.00, FW1110.00-FW1110.30, and FW1060.00-FW1060.80. Use IBM tools or commands like 'lsmcode -r' on AIX/Linux to list firmware versions.

Impact Analysis

An attacker exploiting this vulnerability can gain complete control over the host system and all its partitions. This allows unauthorized access to sensitive data, modification of system configurations, and disruption of services, resulting in severe operational and security consequences.

Compliance Impact

This vulnerability can lead to unauthorized access and control over systems, which may result in data breaches. Such breaches can violate compliance requirements under GDPR, HIPAA, and other regulations, potentially leading to legal penalties, loss of trust, and reputational damage.

Mitigation Strategies

Apply the provided firmware updates for your Power Systems model, such as FW1110.31(1110_134), FW1120.01(1120_167), or newer versions as specified by IBM.
Check the IBM support page for your specific model to confirm the correct firmware version and installation instructions.
Since no workarounds are available, updating the firmware is the only mitigation method recommended by IBM.
