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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/InternLM/lmdeploy","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/pytorch/engine/engine_loop.py#L560-L564","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/pytorch/utils.py#L187-L214","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/serve/openai/endpoints/completions.py#L130-L136","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/issues/4965","tags":[]},{"url":"https://www.vulncheck.com/advisories/internlm-lmdeploy-through-0.17.0-assertion-denial-of-service","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/issues/4965","tags":[]}],"exploitRefs":[{"url":"https://github.com/InternLM/lmdeploy","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/pytorch/engine/engine_loop.py#L560-L564","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/pytorch/utils.py#L187-L214","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/blob/v0.17.0/lmdeploy/serve/openai/endpoints/completions.py#L130-L136","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/issues/4965","tags":[]},{"url":"https://github.com/InternLM/lmdeploy/issues/4965","tags":[]}],"hasPoc":true,"ai":null}
