CVE-2026-17093 evidence review
IBM Power Systems Firmware
IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, FW950.00 through FW950.H2, OP940.00 through OP940.a1 (Power9), and OP940.00 - OP940.81 (Power HMC) is affected by a vulnerability in host firmware configuration parsing. An attacker with service-level access to the BMC/FSP can supply specially crafted configuration data, compromising the host firmware boot stage and everything subsequently loaded by it, resulting in a confidentiality, integrity, and availability impact to the managed system.
This record remains available for product and version identification, but it is not presented as a complete remediation procedure. Confirm the affected range and the supported fix in a direct vendor advisory before changing production systems.
Identify the product and installed version
Record whether IBM Power Systems Firmware is present, where it is installed, and which interfaces are exposed.
- Record the product name, package or appliance identifier, and installed version.
- Identify internet-facing, administrative, API, and internal access paths.
- Preserve the pre-change configuration and relevant service logs.
Compare the affected range
Use the current record as an identification aid: >= FW1120.00, >= FW1110.00 <= FW1110.30, >= FW1060.00 <= FW1060.80, >= FW950.00 <= FW950.H2, >= OP940.00 <= OP940.a1, >= OP940.00 <= OP940.81. Resolve incomplete inventory results before deciding that an asset is unaffected.
Verify the authoritative remediation source
Open the linked source material and locate a direct vendor advisory for this CVE. Confirm the supported fixed release and product-specific update path before making a production change.
Operational boundary
This page does not replace the vendor advisory, support contract, change-management process, or recovery plan. Do not infer that an asset is unaffected from an incomplete inventory query or a missing fixed-version field.
