CVE-2026-17413 is a medium-severity vulnerability rated 5.1/10 on the CVSS scale. 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 RTAS firmware-to-OS interface. An attacker with administrator-level (root) access to a logical partition can send a specially crafted request to partition firmware, causing the partition to crash and become unavailable. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
Description
