| Título | SGLang Project (sgl-project) SGLang 0.5.10.post1 Reachable Assertion |
|---|
| Descripción | SGLang through 0.5.10.post1, when launched with --enable-lora, does not enforce the --max-loras-per-batch N limit at scheduler batch-construction time. When concurrent inference requests in a single scheduling round target more than N distinct LoRA adapter UIDs (including base-model requests with no lora_path, which count as a distinct UID), the scheduler assembles a batch with N+1 adapters. This triggers a reachable assertion (assert len(cur_uids) <= self.max_loras_per_batch) in python/sglang/srt/lora/lora_manager.py that is evaluated by the model runner. The unhandled AssertionError terminates the scheduler process, SIGQUIT propagates to the server, and the server becomes permanently unresponsive until restarted. A remote attacker with network access to the inference HTTP endpoint can cause denial of service by sending a small burst of completion requests across more adapters than the configured cap. No authentication is required in default deployments. |
