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.\n\n## Affected\n\n- `power_system_s1122_(9824-22a)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_s1122_(9824-22a)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_s1124_(9824-42a)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_s1124_(9824-42a)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_s1122s_(9824-22b)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_s1122s_(9824-22b)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_s1114_(9824-41b)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_s1114_(9824-41b)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_l1122_(9856-22h)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_l1122_(9856-22h)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_l1124_(9856-42h)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_l1124_(9856-42h)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_e1150_(9043-mru)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_e1150_(9043-mru)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_s1112_(9242-21b)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_s1112_(9242-21t)_firmware >= fw1120.00, < fw1120.02`\n- `power_system_e1080_(9080-hex)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_s1022_(9105-22a)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_s1024_(9105-42a)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_s1022s_(9105-22b)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_s1014_(9105-41b)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_l1022_(9786-22h)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_l1024_(9786-42h)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_e1050_(9043-mrx)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_s1012_(9028-21b)_firmware >= fw1060.00, < fw1060.82`\n- `power_system_e1180_(9080-heu)_firmware >= fw1110.00, < fw1110.32`\n- `power_system_e1180_(9080-heu)_firmware >= fw1120.00, < fw1120.02`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `power_system_s1122_(9824-22a)_firmware fw1120.02`\n- `power_system_s1124_(9824-42a)_firmware fw1120.02`\n- `power_system_s1122s_(9824-22b)_firmware fw1120.02`\n- `power_system_s1114_(9824-41b)_firmware fw1120.02`\n- `power_system_l1122_(9856-22h)_firmware fw1120.02`\n- `power_system_l1124_(9856-42h)_firmware fw1120.02`\n- `power_system_e1150_(9043-mru)_firmware fw1120.02`\n- `power_system_s1112_(9242-21b)_firmware fw1120.02`\n- `power_system_s1112_(9242-21t)_firmware fw1120.02`\n- `power_system_e1080_(9080-hex)_firmware fw1060.82`\n- `power_system_s1022_(9105-22a)_firmware fw1060.82`\n- `power_system_s1024_(9105-42a)_firmware fw1060.82`\n- `power_system_s1022s_(9105-22b)_firmware fw1060.82`\n- `power_system_s1014_(9105-41b)_firmware fw1060.82`\n- `power_system_l1022_(9786-22h)_firmware fw1060.82`\n- `power_system_l1024_(9786-42h)_firmware fw1060.82`\n- `power_system_e1050_(9043-mrx)_firmware fw1060.82`\n- `power_system_s1012_(9028-21b)_firmware fw1060.82`\n- `power_system_e1180_(9080-heu)_firmware fw1120.02`","depth":"sunlit","depthScore":18,"depthScoreParts":{"impact":17.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
