CVE-2026-16938
6.9 · MEDIUMOverview
CVE-2026-16938 is a medium-severity vulnerability affecting ibm power_system_e1080_\(9080-hex\)_firmware. It was published on August 19, 2026 and has a CVSS 3.1 base score of 6.9 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.9, rated MEDIUM. 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, and FW950.00 through FW950.H2 is affected by a vulnerability in access controls over privileged system configuration operations on the FSP. An attacker with authenticated administrator-level access to the FSP can place the managed system into a non-production operational mode, allowing certain system components to be disabled. This condition persists across FSP resets and requires explicit operator intervention — clearing the affected configuration — to restore normal operation. Successful exploitation results in an availability impact to the managed system.
Remediation
Check the references section for vendor advisories and patches from ibm. Update power_system_e1080_\(9080-hex\)_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.
