SCA: security update for vllm (GHSA-hjq4-87xh-g4fv)

critical Tenable Cloud Security Plugin ID 427736

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - vLLM, an inference and serving engine for large language models (LLMs), has an issue in versions 0.6.5
 through 0.8.4 that ONLY impacts environments using the `PyNcclPipe` KV cache transfer integration with the
 V0 engine. No other configurations are affected. vLLM supports the use of the `PyNcclPipe` class to
 establish a peer-to-peer communication domain for data transmission between distributed nodes. The GPU-
 side KV-Cache transmission is implemented through the `PyNcclCommunicator` class, while CPU-side control
 message passing is handled via the `send_obj` and `recv_obj` methods on the CPU side.​ The intention was
 that this interface should only be exposed to a private network using the IP address specified by the
 `--kv-ip` CLI parameter. The vLLM documentation covers how this must be limited to a secured network. The
 default and intentional behavior from PyTorch is that the `TCPStore` interface listens on ALL interfaces,
 regardless of what IP address is provided. The IP address given was only used as a client-side address to
 use. vLLM was fixed to use a workaround to force the `TCPStore` instance to bind its socket to a specified
 private interface. As of version 0.8.5, vLLM limits the `TCPStore` socket to the private interface as
 configured. (CVE-2025-47277)
