Executive Summary

This vulnerability affects IBM PowerVM Hypervisor firmware versions FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3. It involves a flaw in the partition resource dump interface that allows an authenticated administrator-level attacker with access to the HMC or service processor to obtain a limited snapshot of a partition's processor state, resulting in a confidentiality impact.

Detection Guidance

Detection requires checking the firmware version of IBM PowerVM Hypervisor. Use HMC or service processor interfaces to verify if the installed version matches affected ranges (FW1120.00-FW1120.01, FW1110.00-FW1110.31, FW1060.00-FW1060.81, FW950.00-FW950.H3). No specific commands are provided in the resources.

Impact Analysis

An attacker could exploit this vulnerability to gain access to sensitive processor state information of a partition, potentially leading to unauthorized disclosure of system data. This could compromise the confidentiality of the managed system's operations and data.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR, HIPAA, or other regulations that mandate strict data confidentiality and protection controls.

Mitigation Strategies

Apply the firmware updates provided by IBM for your specific Power System model. The resources indicate no workarounds exist, so updating to the recommended non-vulnerable firmware versions is the only mitigation.
