An attacker with service access to the service processor can supply a maliciously crafted code update image, allowing arbitrary code to be executed on the host system. Successful exploitation could result in a confidentiality, integrity, and availability impact to the affected host system.","state":0,"publishedAt":"2026-10-12T20:52:20.625+00:00","modifiedAt":"2026-10-13T11:57:49.528+00:00","affected":[{"ecosystem":"Vendor product","name":"PowerVM Hypervisor","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"IBM\",\n                    \"product\": \"PowerVM Hypervisor\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"FW1120.00\",\n                            \"lessThanOrEqual\": \"FW1120.01\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"FW1110.00\",\n                            \"lessThanOrEqual\": \"FW1110.31\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"FW1060.00\",\n                            \"lessThanOrEqual\": \"FW1060.81\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1120.00:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1120.00.0:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1120.01:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1120.01.0:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1110.00:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1110.00.0:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1110.31:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1110.31.0:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1060.00:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1060.00.0:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1060.81:*:*:*:*:*:*:*\",\n                        \"cpe:2.3:a:ibm:powervm_hypervisor:fw1060.81.0:*:*:*:*:*:*:*\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.2,"severity":"HIGH"}],"references":["https://www.ibm.com/support/pages/node/7290129"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96263","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96263","identifiers":["CVE-2026-96263"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
