{"schema":"threatline.record/2","record":{"id":"CVE-2026-96265","aliases":[],"summary":"IBM Power Systems Firmware Improper Memory Buffer Restriction","details":"IBM Power Systems Firmware FW1060.00 through FW1060.81 is affected by a vulnerability in the service processor mailbox interface. 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.","categories":["Containers & cloud"],"product":"PowerVM Hypervisor","vendor":"IBM","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96265","source_modified_at":"2026-10-13T11:57:49.766Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"PowerVM Hypervisor","vendor":"IBM","versions":[{"status":"affected","version":"FW1060.00","lessThanOrEqual":"FW1060.81","versionType":"semver"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00169,"percentile":0.05934,"score_date":"2026-10-23"},"published_at":"2026-10-12T20:52:00.904Z","modified_at":"2026-10-13T11:57:49.766Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-96265","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T11:57:49.766Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96265","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.ibm.com/support/pages/node/7290124","tags":["vendor-advisory","patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-13T03:55:39.210521Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-13T11:57:49.766Z","content_hash":"97a75f6adbec7331bc5aa8561c35367db2b16feac88f69da099596a75093cdd0"}}
