Published Aug 19, 2026 ibm CWE-121 EPSS 0.20% (10th pctl)

Overview

CVE-2026-18681 is a medium-severity vulnerability affecting ibm power_system_s922_\(9009-22g\)_firmware. It was published on August 19, 2026 and has a CVSS 3.1 base score of 6.8 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

IBM Server Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the FSP firmware update process. An attacker with authenticated administrator-level access to the FSP can, under specific conditions, execute arbitrary code, resulting in a confidentiality, integrity, and availability impact.

Remediation

Check the references section for vendor advisories and patches from ibm. Update power_system_s922_\(9009-22g\)_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
