Process crash via malformed frame handling
Published Oct 12, 2026 · Updated Oct 12, 2026
DoS in IBM Maximo AI Service 9.1.0 and 9.2.0 allows remote attackers to terminate the host process via malformed frames. The frame handler mishandles malformed input; the specific parser, protocol, and failing operation are not disclosed in the retrieved CNA record. Exploitation requires network reachability but no credentials or user interaction, and the reported consequence is process termination rather than host reboot.
