CVE-2025-6208
Description
A flaw was found in llama_index. The SimpleDirectoryReader component loads all files from a specified directory into memory before applying a user-defined file limit. This resource management flaw allows an attacker to cause uncontrolled memory consumption. This can lead to memory exhaustion and degraded performance, resulting in a Denial of Service (DoS) for systems utilizing the affected component.
Statement
This MODERATE impact flaw in llama_index affects Red Hat Ansible Automation Platform and OpenShift Lightspeed. The SimpleDirectoryReader component loads all files from a specified directory into memory before applying any user-defined file limits. This can lead to uncontrolled memory consumption, potentially causing a Denial of Service due to memory exhaustion and degraded performance in resource-constrained environments.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
