CVE-2026-16930: CWE-862 Missing Authorization in IBM Power Systems Firmware
IBM Power Systems Firmware versions FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 contain a missing authorization vulnerability in the interface between the BMC/FSP and the host system. An attacker with service or root access to the BMC/FSP can execute arbitrary code on the host, gaining full control over the host and all hosted partitions. This results in a high-impact compromise of confidentiality, integrity, and availability.

Technical Summary
CVE-2026-16930 is a missing authorization vulnerability (CWE-862) in IBM Power Systems Firmware affecting versions FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80. The flaw exists in the interface between the Baseboard Management Controller (BMC)/Flexible Service Processor (FSP) and the host system. An attacker with elevated privileges (service account or root) on the BMC/FSP can leverage this vulnerability to execute arbitrary code on the host system, thereby gaining full control over the host and all hosted partitions. The vulnerability has a CVSS v3.1 score of 8.2, indicating high severity with impacts to confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an attacker with high privileges on the BMC/FSP to execute arbitrary code on the host system, resulting in complete compromise of the host and all hosted partitions. This leads to full loss of confidentiality, integrity, and availability of the affected systems.
Mitigation Recommendations
No patch or remediation information is currently available. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is released, restrict and monitor access to the BMC/FSP interfaces to prevent unauthorized or unnecessary elevated access.
