LOW
The severity is rated as LOW because this is not a vulnerability but an internal tool for monitoring. There are no direct security implications, and it does not introduce any known vulnerabilities into the Proxmox environment.

This advisory discusses the development of a hardware monitoring dashboard for Proxmox nodes by an engineer who desired more visibility into their system's operational state, particularly around fan speeds and temperatures. The dashboard provides real-time data on various metrics such as CPU package and per-core temperatures, NVMe and chipset temps, power consumption details, and system load indicators. All data is sourced directly from the Linux kernel interfaces like `/sys/class/hwmon`, EC registers, sysfs, and procfs, ensuring minimal dependencies and a pure Python implementation. This tool serves as an internal monitoring solution that can be crucial for maintaining optimal operational conditions in Proxmox environments, reducing the risk of hardware failures due to overheating.

Affected Systems
  • Proxmox VE
  • ASUS Motherboards
Remediation
  • Install the hardware monitor script from GitHub (if available).
  • Ensure Python environment compatibility.
  • Run the script periodically or as a service for continuous monitoring.
Stack Impact

Minimal direct impact. This tool is a monitoring dashboard with no inherent security issues, but it can indirectly improve system stability and security by allowing administrators to better manage hardware conditions.
