    CVE-2026-93306

    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.
