Client connecting to a MQ Queue Manager can cause a SIGSEGV in the AMQRMPPA channel process terminating it.CVE-2025-12755ibmmq operator+1EPSS score0.13%
IBM MQ Operator (SC2 v3.2.0–3.8.1, LTS v2.0.0–2.0.29) and IBM‑supplied MQ Advanced container images (across affected SC2, CD, and LTS 9.3.x–9.4.x releases) contain a vulnerability where log messages are not properly neutralized before being written to log files. This flaw could allow an unauthorized user to inject malicious data into MQ log entries, potentially leading to misleading logs, log manipulation, or downstream log‑processing issues.
