Linux Kernel Aspeed VHub Refcount Leak Vulnerability

A refcount leak vulnerability has been identified in the Linux kernel's USB Aspeed virtual hub component. The issue arises in the 'ast_vhub_init_desc()' function, where the reference obtained from 'of_get_child_by_name()' is not properly released, leading to a memory management flaw.

Impact

Exploitation of this vulnerability causes a memory leak, which can potentially be exploited to manipulate memory management, although no direct exploitation vector is mentioned.
