IBM does not want to enable a malicious attacker with sufficient knowledge to craft an exploit of the vulnerability. Note: After December 31, 2025, 11.1 and 10.5 versions of Db2 will not have security fixes made available as they will reach EoS.
Workaround
Workarounds and Mitigations For JCC applications, set queryCloseImplicit property to 2 for the connections. For, CLI and ODBC applications, set SQL_ATTR_EARLYCLOSE property to SQL_EARLYCLOSE_OFF for the statements. Manually recycle connections either by forcing the application handles or by making an application side change (a refresh of the connection pool). You can find the application handles that use most FCM buffers by running db2pd -fcm -member x (look for the highest buffer consumer) and then force.
