CVE-2026-10747: CWE-122 Heap-based Buffer Overflow in IBM MQ Appliance
IBM MQ Appliance could allow a remote attacker to cause a denial of service or potentially execute arbitrary code due to a heap buffer overflow in protocol message processing before authentication.
AI Analysis
Technical Summary
IBM MQ Appliance version 10.0.0.0 contains a heap-based buffer overflow vulnerability (CWE-122) in the protocol message processing component that is triggered before authentication. This allows a remote attacker to send crafted messages that can overflow the heap buffer, potentially leading to denial of service or arbitrary code execution. The vulnerability is remotely exploitable without authentication or user interaction, and it affects the confidentiality, integrity, and availability of the system.
Potential Impact
Successful exploitation can result in a complete compromise of the affected IBM MQ Appliance, including denial of service and arbitrary code execution with system-level impact. The vulnerability allows an unauthenticated remote attacker to fully control the device, impacting confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict network access to the affected appliance and monitor for unusual activity related to protocol message processing.
