Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2026-115914 (opens in a new tab)How to fix?
Upgrade vllm to version 0.32.0 or higher.
Overview
vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs
Affected versions of this package are vulnerable to Reachable Assertion via _parse_and_validate_image_input in deepseek_ocr.py and deepseek_ocr2.py, where a zero-sum pixel tensor causes the function to return None, which then triggers an AssertionError in sanity_check_mm_encoder_outputs and crashes the engine worker. An authenticated attacker can submit an image whose pixel values sum to zero to bring down the inference server.
