Linux Kernel up to 6.2.2 pinctrl of_find_node_by_phandle reference count

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 6.2.2. This affects the function of_find_node_by_phandle of the component pinctrl. The manipulation with an unknown input leads to a reference count vulnerability. CWE is classifying the issue as CWE-911. The product uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups of_find_node_by_phandle() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2023-54111 since 12/24/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 280037 (Linux Distros Unpatched Vulnerability : CVE-2023-54111), which helps to determine the existence of the flaw in a target environment.
