{"cve":"CVE-2026-19492","nvd":{"published":"2026-09-24T15:17:20.553","modified":"2026-09-30T15:40:51.593","status":"Analyzed","description":"IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, and FW1060.00 through FW1060.81 is affected by a vulnerability in a hypervisor call interface. An attacker with root access to a guest partition can read a limited amount of hypervisor memory, potentially exposing sensitive data belonging to the hypervisor or other guest partitions hosted on the same system, resulting in a confidentiality impact. The attacker has no control over which memory contents are returned. This vulnerability is of particular concern in multi-tenant environments where guests may run arbitrary OS images.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N","score":3.2},"cwes":["CWE-457"],"references":["https://www.ibm.com/support/pages/node/7289137"],"products":["ibm:power_system_e1050_\\(9043-mrx\\)_firmware","ibm:power_system_e1080_\\(9080-hex\\)_firmware","ibm:power_system_e1150_\\(9043-mru\\)_firmware","ibm:power_system_e1180_\\(9080-heu\\)_firmware","ibm:power_system_l1022_\\(9786-22h\\)_firmware","ibm:power_system_l1024_\\(9786-42h\\)_firmware","ibm:power_system_l1122_\\(9856-22h\\)_firmware","ibm:power_system_l1124_\\(9856-42h\\)_firmware","ibm:power_system_s1012_\\(9028-21b\\)_firmware","ibm:power_system_s1014_\\(9105-41b\\)_firmware","ibm:power_system_s1022_\\(9105-22a\\)_firmware","ibm:power_system_s1022s_\\(9105-22b\\)_firmware","ibm:power_system_s1024_\\(9105-42a\\)_firmware","ibm:power_system_s1112_\\(9242-21b\\)_firmware","ibm:power_system_s1112_\\(9242-21t\\)_firmware","ibm:power_system_s1114_\\(9824-41b\\)_firmware","ibm:power_system_s1122_\\(9824-22a\\)_firmware","ibm:power_system_s1122s_\\(9824-22b\\)_firmware","ibm:power_system_s1124_\\(9824-42a\\)_firmware"],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-19492","score":0.00115,"percentile":0.01538,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
