AI-suggested

Until an official fix is released, organizations should consider restricting network access to the Db2 service, especially from untrusted networks, and monitor for unusual activity related to DRDA handshake attempts. Follow IBM's official communications for updates on patches or mitigations.

Description

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.4 is vulnerable to remote code execution due to improper pre-auth DRDA handshake handling.
