CVE-2026-96262— IBM Power Systems Firmware Buffer Overflow
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 Power Systems 固件 FW1060.00 至 FW1060.81 受到服务处理器邮箱接口中漏洞的影响。具备经过认证的服务级别访问权限的攻击者可以向 FSP（Flexible Service Processor）发送特制的邮箱消息，从而导致主机固件运行时属性存储发生溢出，进而在主机固件运行时环境中执行任意代码。攻击者由此获得对受管系统内存及硬件接口的完全访问权限，导致受管系统的机密性、完整性和可用性受到严重影响。

Vulnerability Title
IBM Power Systems Firmware Buffer Overflow
Source: CVE Program / CVE List V5
Vulnerability Description
IBM Power Systems Firmware FW1060.00 through FW1060.81 is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the FSP can send a specially crafted mailbox message to overflow host firmware runtime attribute storage, allowing arbitrary code to be executed in the host firmware runtime. This gives the attacker full access to the managed system's memory and hardware interfaces, resulting in a confidentiality, integrity, and availability impact to the managed system.
