CVE-2026-12670Medium· 5.3IBM MQ Denial of Service
IBM MQ could allow an authenticated attacker to cause a denial of service through a specially crafted message that triggers excessive memory operations during character set conversion.
CVE-2026-12669Low· 3.1IBM MQ Out-of-bounds Read
IBM MQ could allow an authenticated attacker to trigger a minor out-of-bounds read when sending malformed compressed data, though the data is not disclosed and the request is rejected.
CVE-2026-12665High· 8.1IBM MQ Buffer Overflow
IBM MQ could allow a remote attacker to execute arbitrary code due to a stack buffer overflow when processing TLS certificates with malformed distinguished names during channel connection establishment.
CVE-2026-12660Low· 2.7IBM MQ Path Traversal
IBM MQ Web Console could allow an authenticated administrator to write files outside the intended directory due to improper path validation.
CVE-2026-12343Medium· 6.5IBM MQ Denial of Service
IBM MQ could allow an authenticated attacker to cause a denial of service due to improper validation of RFH2 message header fields in queued publish/subscribe operations.
CVE-2026-12155Medium· 6.5IBM MQ Deserialization of Untrusted Data
