CVE-2026-17097— Power System Improper Validation

Quick assessment

Affected
IBM PowerVM Hypervisor
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IBM powervm hypervisor是美国IBM公司的一款企业级虚拟化管理程序。 IBM PowerVM Hypervisor FW1120.00版本、FW1110.00至FW1110.30版本、FW1060.00至FW1060.80版本和FW950.00至FW950.H2版本存在输入验证错误漏洞，该漏洞源于PowerVM管理程序调用接口存在缺陷，具有客户分区root权限的攻击者可发出特制管理程序调用，导致虚拟处理器永久无响应，需要完整平台重新IPL才能恢复，在某些情况下还可能导致向管理程序或分区

Vulnerability Title
Power System Improper Validation
Source: CVE Program / CVE List V5
Vulnerability Description
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.
