CVE-2022-43902Network attack vector

Authenticated service interruption via crafted administrative messages

Published Mar 1, 2023 · Updated Mar 6, 2025

Denial of service in IBM MQ Server 9.2 and 9.3 allows remote authenticated users to interrupt service via crafted PCF or MQSC messages. The Server component processes a specially crafted payload in an authorized PCF or MQSC command, but IBM has not disclosed the faulty operation. Sufficient MQ permissions are required; public evidence does not identify whether the interruption is a crash or hang.
