FKIE_CVE-2022-50444

Vulnerability from fkie_nvd - Published: 2025-10-01 12:15 - Updated: 2026-06-17 05:23
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: clk: tegra20: Fix refcount leak in tegra20_clock_init of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
