CVE-2024-39743Network attack vector

Remote service interruption via incorrect memory de-allocation

Published Jul 8, 2024 · Updated Aug 2, 2024

Denial of service in IBM MQ Operator 2.0.24 and 3.2.2 allows remote attackers to exhaust memory in Developer Edition containers. IBM attributes retained memory consumption to incorrect memory de-allocation but does not identify the affected function, object, or request path. Exposure requires a Developer Edition queue manager container, and exhausting its available memory can interrupt that container's service.
