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.","published":"2026-09-24T15:17:21.000Z","lastModified":"2026-09-30T15:40:52.000Z","status":"Analyzed","sourceIdentifier":"psirt@us.ibm.com","cvss":{"version":"3.1","score":3.2,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N"},"cwe":["CWE-457"],"affected":["ibm/power system s1122 \\(9824-22a\\) firmware","ibm/power system s1124 \\(9824-42a\\) firmware","ibm/power system s1122s \\(9824-22b\\) firmware","ibm/power system s1114 \\(9824-41b\\) firmware","ibm/power system l1122 \\(9856-22h\\) firmware","ibm/power system l1124 \\(9856-42h\\) firmware","ibm/power system e1150 \\(9043-mru\\) firmware","ibm/power system s1112 \\(9242-21b\\) firmware","ibm/power system s1112 \\(9242-21t\\) firmware","ibm/power system e1080 \\(9080-hex\\) firmware","ibm/power system s1022 \\(9105-22a\\) firmware","ibm/power system s1024 \\(9105-42a\\) firmware","ibm/power system s1022s \\(9105-22b\\) firmware","ibm/power system s1014 \\(9105-41b\\) firmware","ibm/power system l1022 \\(9786-22h\\) firmware","ibm/power system l1024 \\(9786-42h\\) firmware","ibm/power system e1050 \\(9043-mrx\\) firmware","ibm/power system s1012 \\(9028-21b\\) firmware","ibm/power system e1180 \\(9080-heu\\) firmware"],"epss":{"score":0.00115,"percentile":0.01538,"date":"2026-10-26","history":[{"date":"2026-09-25","score":0.00115,"percentile":0.01386}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.11%).
