## Overview

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. An attacker with root access to a partition can send a specially crafted request to the partition firmware runtime, causing it to crash with possible memory corruption.
