CVE-2026-11831
IBM MQ could allow an authenticated attacker to cause a limited denial of service and obtain very limited information about process memory layout due to an out-of-bounds read when processing a specially crafted client request.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
