Summary
A flaw was found in vLLM. The LlavaOnevision2 processor loader incorrectly ignores the `trust_remote_code` parameter, which is designed to prevent the execution of untrusted code.
This oversight allows an attacker to craft a malicious model containing arbitrary code. When such a model is loaded, the code executes with the vLLM process's authority, leading to remote code execution.
Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-94.
Affected Red Hat products: Red Hat AI Inference Server; Red Hat Enterprise Linux AI (RHEL AI) 3; Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.
