CVE-2024-41761Network attack vector

Authenticated server crash via excessive memory allocation

Published Nov 23, 2024 · Updated Nov 23, 2024

Denial of service in IBM Db2 10.5, 11.1, and 11.5 allows remote authenticated users to crash the server with a crafted query. IBM has not published the query form, affected code path, or exact allocation operation; its CWE-789 mapping identifies an excessive-size memory allocation. Valid Db2 credentials and high-complexity conditions are required, and the reported consequence is limited to a server crash.
