NVD Description

Note: Versions mentioned in the description apply only to the upstream rhelai1/instructlab-nvidia-rhel9 package and not the rhelai1/instructlab-nvidia-rhel9 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A vulnerability was found in the ilab model serve component, where improper handling of the best_of parameter in the vllm JSON web API can lead to a Denial of Service (DoS). The API used for LLM-based sentence or chat completion accepts a best_of parameter to return the best completion from several options. When this parameter is set to a large value, the API does not handle timeouts or resource exhaustion properly, allowing an attacker to cause a DoS by consuming excessive system resources. This leads to the API becoming unresponsive, preventing legitimate users from accessing the service.
