Doc Text:
A flaw was found in vLLM. A remote attacker can trigger a Denial of Service (DoS) by submitting a request with excessively large frame rate and frame count options for the GLMGA video backend. Because the application constructs intermediate frame index lists without proper upper bounds, processing these requests consumes disproportionate CPU and memory resources, potentially causing service degradation or unresponsiveness.

Description OSIDB Bzimport 2026-10-05 23:11:18 UTC
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.
