CVE-2026-17100

TITLE

IBM of IBM POWER HARDWARE MANAGEMENT CONSOLE (7063-CR2) Vulnerabilities related to out-of-bounds writes in multiple firmware and other products

Trust: 0.8

sources: JVNDB: JVNDB-2026-030118

DESCRIPTION

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, and OP940.00 - OP940.81 is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the BMC/FSP can exploit this vulnerability, allowing arbitrary code to be executed in the host firmware runtime, giving full control over the managed system, resulting in a confidentiality, integrity, and availability impact to the managed system. An attacker with authenticated service level access rights can... - All information handled by the software may be overwritten. - The software may completely shut down
