CVE-2024-47118Network attack vector

Server crash via crafted query buffer overflow

Published Nov 7, 2025 · Updated Nov 7, 2025

Stack-based buffer overflow in IBM Db2 Server allows remote authenticated users to crash the database service via a crafted query. The query-processing path writes beyond a stack buffer when handling crafted statement data; IBM has not disclosed the affected function. Successful exploitation requires low-privileged database access and interrupts availability on affected 10.5.0 through 10.5.11, 11.1.0 through 11.1.4.7, 11.5.0 through 11.5.9, and 12.1.0 through 12.1.2 servers.
