# CVE-2026-126396: vLLM from 0.24.0 before 0.31.0 Resource Exhaustion via MiniMax M3 min_pixels

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

vLLM from 0.24.0 before 0.31.0 contains a resource exhaustion vulnerability in the MiniMax M3 VL video processor, which accepts request-level min_pixels without range or min_pixels <= max_pixels validation. Its video-wide pixel budget is enforced only when max_long_side_pixel is set, and that value defaults to None. API clients can supply a large min_pixels via mm_processor_kwargs to enlarge every decoded frame, causing excessive CPU and host-memory consumption that may disrupt workers or the service.
