{"id":"CVE-2026-17503","published":"2026-09-24T14:17:12.063","lastModified":"2026-09-24T15:17:19.717","description":"IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the partition firmware runtime boot configuration. An attacker with root access to a partition can maliciously alter partition nvram, causing the partition to fail to boot. This condition persists until operator intervention — deleting and recreating the partition configuration — to restore normal operation. Successful exploitation results in an integrity and availability impact.","cvssScore":5.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H","cwes":["CWE-20"],"vendors":[],"products":[],"references":[{"url":"https://www.ibm.com/support/pages/node/7289133","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
