      <title>CVE-2024-8939 — Vllm: denials of service in vllm json web api</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-8939</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; vllm, Red Hat Enterprise Linux AI (RHEL AI)&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
