Description
Protection mechanism failure for some LLM-on-Ray before version 1.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

AI Analysis

Impact

The vulnerability is a protection mechanism failure in LLM‑on‑Ray before version 1.0 that allows an unprivileged application running in user mode to acquire the privileges of a privileged user. An attacker can exploit this local flaw with low complexity and only passive user interaction, potentially reading, modifying or deleting sensitive data and disrupting operations, thereby causing high confidentiality, integrity and availability impacts.

Affected Systems

Deployments of LLM‑on‑Ray with versions earlier than 1.0 are affected. The product appears to be a specialized or internal solution, and no public patch or detailed advisory has been released beyond the Intel reference.

Risk and Exploitability

The CVSS score of 5.4 indicates moderate severity. The EPSS score of less than 1% suggests a very low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Although it requires local access and low complexity, the potential for catastrophic confidentiality, integrity and availability damage warrants a careful assessment of the environment.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade LLM‑on‑Ray to version 1.0 or later to apply the protection mechanism fix.
  • Enforce least‑privilege controls so that unprivileged processes cannot invoke privileged modules or APIs.
  • Use operating‑system hardening to limit local access, such as disabling unnecessary services, enabling mandatory access control, and restricting user session permissions.
