CVE-2022-49712 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: lpc32xx_udc: Fix refcount leak in lpc32xx_udc_probe of_parse_phandle() 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. of_node_put() will check NULL pointer.
A refcount leak vulnerability has been identified in the Linux kernel's LPC32XX USB gadget driver. The issue arises in the 'lpc32xx_udc_probeof_parse_phandle()' function, which returns a node pointer with an incremented reference count. The driver fails to release this reference properly when the node is no longer needed, leading to a memory leak. The missing reference count management has been addressed by adding the necessary 'of_node_put()' calls to prevent the leak.
