Virtualization Management Interface Denial of Service

Publication date: 2026-08-19

Last updated on: 2026-08-25

Assigner: IBM Corporation

Description
IBM Virtualization Management Interface FW1110.00 through FW1110.30, FW1120.00 through FW1120.00, and FW1060.00 through FW1060.80 is affected by a vulnerability in the Virtualization Management Interface (VMI). An attacker with authenticated administrator-level access can cause the VMI to crash. The VMI will restart automatically; however, repeated exploitation could result in a sustained availability impact.

Exploitability

CWE
CWE Icon
KEV
KEV Icon
CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This vulnerability affects IBM Virtualization Management Interface (VMI) firmware versions FW1110.00 through FW1110.30, FW1120.00, and FW1060.00 through FW1060.80. An attacker with authenticated administrator-level access can crash the VMI, causing it to restart automatically. Repeated exploitation may lead to sustained availability issues.

Detection Guidance

Detection requires checking the firmware version of IBM Power Systems. Use IBM's firmware update tools or commands like 'lsmcode -r' on AIX/Linux to verify if your system runs affected versions FW1110.00-FW1110.30, FW1120.00, or FW1060.00-FW1060.80.

Impact Analysis

The primary impact is service disruption due to VMI crashes and restarts. If exploited repeatedly, it could cause prolonged downtime, affecting virtualization management operations. However, exploitation requires authenticated administrator access, limiting the risk to authorized users.

Compliance Impact

This vulnerability primarily impacts system availability by allowing an authenticated attacker to crash the Virtualization Management Interface (VMI), potentially causing sustained downtime. While it does not directly expose data, prolonged unavailability of management interfaces could interfere with logging, monitoring, and access controls required by GDPR and HIPAA. Compliance may be affected if systems fail to meet uptime or audit requirements due to repeated crashes.

Mitigation Strategies

Apply the latest firmware updates immediately: FW1110.31(1110_155), FW1120.01(1120_190), or newer for Power 11 systems, and FW1060.81(1060_191) or newer for Power 10 systems. Download updates from IBM Fix Central.
