Description

A flaw was found in the Linux kernel's drm/logicvc component. The logicvc_drm_config_parse() function, when processing device configurations, fails to properly release a reference to a device node. This oversight leads to a device node reference leak, which can result in resource exhaustion over time and potentially lead to a Denial of Service (DoS) condition.
