InternLM LMDeploy through 0.17.0 Memory Exhaustion via Session ID Mismatch

Published Sep 17, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
InternLM LMDeploy through 0.17.0 in DistServe prefill/decode disaggregation mode fails to release scheduler sessions because the proxy uses user-facing session IDs instead of internal scheduler keys. Unauthenticated attackers can send completion requests to the proxy endpoint that accumulate unreleased scheduler metadata and memory until the prefill worker is out-of-memory killed.
