CVE-2022-50032 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: renesas: Fix refcount leak bug In usbhs_rza1_hardware_init(), of_find_node_by_name() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.
A refcount leak vulnerability has been identified in the USB Renesas component of the Linux kernel. The issue arises in the function 'usbhs_rza1_hardware_init()', where 'of_find_node_by_name()' returns a node pointer with an incremented reference count. The vulnerability occurs because the reference count is not properly decremented when the node is no longer needed, leading to a memory management issue.
