CVE-2023-53170:
Linux Kernel vulnerability analysis and mitigation
Overview
In the Linux kernel, a vulnerability (CVE-2023-53170) was identified related to an unnecessary of_node_put call in the felix_parse_ports_node function. The issue was discovered and disclosed on September 15, 2025. This vulnerability affects the Linux kernel's networking subsystem, specifically in the Distributed Switch Architecture (DSA) component (NVD).
Technical details
The vulnerability stems from an unnecessary of_node_put call in the continue path within the felix_parse_ports_node function. This redundant call could potentially cause the child node to be released twice, leading to resource management issues. The issue is specifically located in the net/dsa subsystem of the Linux kernel (NVD).
Impact
The vulnerability could result in resource leaks or other unexpected issues due to the double release of child nodes in the kernel's memory management system (NVD).
Mitigation and workarounds
The vulnerability has been resolved by removing the unnecessary of_node_put call from the continue path in the felix_parse_ports_node function. This fix prevents the double release of child nodes (NVD).
