CVE-2026-18794

Description

A flaw was found in OpenRGB. The OpenRGB network protocol allows a remote attacker to cause out-of-bounds memory reads and writes by sending inconsistent data. This could lead to information disclosure, arbitrary code execution, or a Denial of Service (DoS).

Statement

Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.

Mitigation

To mitigate this issue, restrict network access to the OpenRGB service using firewall rules, allowing connections only from trusted hosts. If the OpenRGB network protocol functionality is not required, consider disabling it through the application's configuration, if available, or uninstalling the OpenRGB package. Ensure any changes to network configurations or service settings are reloaded or the service is restarted for the mitigation to take effect.
