Summary

InternLM LMDeploy through 0.17.0 contains a reachable assertion vulnerability in the DistServe decode migration loop that allows unauthenticated attackers to terminate the inference engine. Attackers can submit a migration_request with an empty remote_block_ids list to trigger an AssertionError that crashes the engine loop and causes subsequent inference requests to fail.

Risk Assessment

An attacker could remotely terminate the inference engine, causing a denial of service for all subsequent requests. Network access to the service is required.

Recommendation

Upgrade LMDeploy to a version later than 0.17.0. Restrict network access to the inference service and consider validating migration_request parameters.
