Linux Kernel DWC2 USB Driver Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's DWC2 USB driver. The issue arises in the 'dwc2_hcd_init' function, where memory is allocated for the host controller driver (HCD). If 'platform_get_resource()' fails, the allocated memory is not properly freed, leading to a memory leak. The vulnerability has been addressed by modifying the error handling to ensure that the memory is released appropriately.

Impact

Exploitation of this vulnerability could lead to a memory leak, causing increased memory usage and potentially leading to a denial-of-service condition.
