8.2 · HIGHOverview
CVE-2026-16933 is a high-severity vulnerability affecting ibm power_system_s1122_\(9824-22a\)_firmware. It was published on August 19, 2026 and has a CVSS 3.1 base score of 8.2 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.2, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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 through OP940.81 (Power HMC) is affected by a vulnerability in the interface between the BMC/FSP and the host system. An attacker with service account or root access to the BMC/FSP can read and write arbitrary regions of host system memory, giving full control over the host system and all hosted partitions, resulting in a confidentiality, integrity, and availability impact.
Remediation
Check the references section for vendor advisories and patches from ibm. Update power_system_s1122_\(9824-22a\)_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.
