Upgrade vLLM to version 0.32.0 or later, where the issue is fixed. No other mitigation is required as the vulnerability is addressed by this official fix.

Description

vLLM versions prior to 0.32.0 contain a resource allocation vulnerability in the Phi-4 multimodal audio encoder. The default use of eager attention causes large attention matrices to be fully materialized in GPU memory when processing long audio clips, leading to quadratic memory consumption. This can result in out-of-memory conditions that terminate the EngineCore process, affecting all users. The issue is resolved in version 0.32.0.
