Overview

CVE-2026-93306 is a high-severity vulnerability affecting ibm power_system_e1080_\(9080-hex\)_firmware. It was published on September 25, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

Technical description

IBM Server Firmware FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the ASMI web interface. An unauthenticated attacker on the management network can send a malformed HTTPS request to ASMI, causing the web server to crash with possible memory corruption and generate an error log. The ASMI web interface will restart automatically; however, repeated exploitation could result in a sustained loss of access to the ASMI management interface, resulting in an integrity and availability impact.

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.
