Description
A reference count leak was found in the Linux kernel's Tegra114 clock driver. The tegra114_clock_init() function calls of_find_matching_node(), which returns a node pointer with an incremented reference count. The code fails to call of_node_put() when the node is no longer needed, resulting in a reference count leak that prevents proper resource cleanup.
Statement
This flaw affects only NVIDIA Tegra114 SoC platforms and results in a minor reference count leak during clock initialization. The leak occurs once at boot time and does not accumulate during runtime, making the practical impact negligible with no exploitable denial of service condition.
