{"id":"CVE-2026-17097","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-17097","summary":"IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the PowerVM hypervisor call…","details":"IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the PowerVM hypervisor call interface. An attacker with root access to a guest partition can issue a specially crafted hypervisor call causing a virtual processor to become permanently unresponsive, requiring a full platform re-IPL to restore normal operation. In some cases this may also cause the guest to inject a small amount of data into hypervisor or partition memory with no attacker control over the target location. Successful exploitation results in an integrity and availability impact to the managed system.","published":"2026-08-19T20:17:12.797","modified":"2026-08-19T20:17:12.797","cvss":{"score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.ibm.com/support/pages/node/7283231"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T20:17:12.797"}}
