Vulnerability from cvelistv5 – Published: 2026-08-19 18:26 – Updated: 2026-08-21 03:57

Title

Power System Out-of-bounds Write

Summary

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.
