CVE-2025-33013

Local information disclosure via uncleared heap memory

Published Jul 24, 2025 · Updated Aug 18, 2025

Information disclosure in IBM MQ Operator LTS 2.0.0 through 2.0.29 and affected CD/SC2 3.x releases allows local users to read residual heap data. The container releases heap allocations without clearing their contents, leaving sensitive bytes available for later inspection or reuse. Local access is required; the published impact is limited to disclosure, with no reported data modification or service interruption.
