An attacker with authenticated service-level access to the FSP can send a specially crafted mailbox message to read or modify arbitrary regions of Hostboot memory, compromising the host firmware boot stack and the hypervisor subsequently loaded by it. Successful exploitation results in a confidentiality, integrity, and availability impact to the managed system.","published":"2026-10-12T21:17:24.190","modified":"2026-10-12T21:17:24.190","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.ibm.com/support/pages/node/7290124"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-12T21:17:24.190"}}
