CVE-2026-57173Network attack vectorHinoki check available

Worker crash via unbounded audio decompression

Published Sep 16, 2026 · Updated Sep 18, 2026

Resource exhaustion in vLLM before 0.24.0 allows remote attackers to crash inference workers through compressed chat audio. The /v1/chat/completions input_audio path calls AudioMediaIO.load_bytes or load_file without supplying the configured decode-duration limit, so a small file expands into a large float32 PCM allocation. Exposure requires an audio-capable model and a reachable chat endpoint; default deployments lack authentication, and exploitation interrupts worker availability.
