CVE-2024-51471Network attack vector

Authenticated service interruption via trace buffer over-read

Published Dec 19, 2024 · Updated Dec 20, 2024

An out-of-bounds read in IBM MQ Appliance 9.3 LTS, 9.3 CD, and 9.4 LTS allows remote authenticated users to interrupt service. Trace processing in the web console accesses information outside the intended buffer size. Network access, valid appliance credentials, and enabled trace are required; exploitation interrupts availability without reported data exposure or modification.
