CVE-2026-105760

vLLM: GLMGA video sampling permits request-driven CPU and memory exhaustion

Published Oct 5, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
vLLM is an inference and serving engine for large language models. Prior to 0.30.0, a caller can use the request-level media_io_kwargs field to select the GLMGA video backend and supply large values for the fps and max_frames options without a strict work ceiling. GLMGA constructs and deduplicates an attacker-sized pre-decode frame-index list, allowing a compact request and tiny valid video to consume disproportionate CPU time and memory in the shared media-loading executor. This issue is fixed in version 0.30.0.

Analysis

AI-generated

Technical impact

vLLM version prior to 0.30.0 allows callers to set large fps and max_frames values in media_io_kwargs for the GLMGA video backend, creating a huge frame-index list that consumes disproportionate CPU time and memory, reflecting vulnerabilities identified as CWE-400 and CWE-770. The resulting resource exhaustion can cause the inference service to become unresponsive, effectively denying service to legitimate users.

Affected Systems

vLLM is an inference engine for large language models. The vulnerability applies to all releases of the vllm-project's vllm package before the 0.30.0 release. Any deployment using earlier versions and referencing the GLMGA video backend is at risk.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity. The EPSS score of <1% indicates a very low likelihood of exploitation, and the vulnerability is not listed in CISA KEV. The likely attack vector is remote, via an API call that supplies a crafted media_io_kwargs payload. An attacker can trigger the vulnerability by submitting a request with oversized fps or max_frames values to the GLMGA backend, causing resource exhaustion in the shared media-loading executor.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade vllm to version 0.30.0 or later.
  • If upgrading is not immediately possible, limit or validate fps and max_frames values for the GLMGA backend to prevent excessive resource use.
  • Continuously monitor CPU and memory usage of the inference service for anomalous spikes that may indicate exploitation.
