CVE-2026-16724: CWE-190 Integer Overflow or Wraparound in IBM Virtualization Management Interface
Description
CVE-2026-16724 is an integer overflow or wraparound vulnerability (CWE-190) in IBM Virtualization Management Interface versions FW1110.00 through FW1110.30, FW1120.00, and FW1060.00 through FW1060.80. An attacker with authenticated administrator-level access can exploit this flaw to cause the Virtualization Management Interface (VMI) to crash. The VMI automatically restarts after a crash, but repeated exploitation could lead to sustained availability issues. The vulnerability has a medium severity rating with a CVSS score of 4.5.

Technical Analysis
IBM Virtualization Management Interface versions FW1110.00 to FW1110.30, FW1120.00, and FW1060.00 to FW1060.80 contain an integer overflow or wraparound vulnerability (CWE-190). This flaw allows an attacker with authenticated administrator privileges to crash the VMI component. Although the VMI restarts automatically after crashing, repeated exploitation may cause prolonged service disruption. The vulnerability does not impact confidentiality or integrity but affects availability.
Potential Impact
The vulnerability allows an authenticated administrator to cause a denial of service by crashing the Virtualization Management Interface. The VMI restarts automatically, so the impact is limited to availability disruption. There is no impact on confidentiality or integrity. Repeated exploitation could result in sustained availability degradation.
Mitigation Recommendations
No official patch or remediation information is provided. Patch status is not yet confirmed — check IBM's vendor advisory for current remediation guidance. Until a fix is available, limit administrator access to trusted personnel to reduce risk of exploitation.
