In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_subset: Fix unbalanced refcnt in geth_free
geth_alloc() increments the reference count, but geth_free() fails to
decrement it. This prevents the configuration of attributes via configfs
after unlinking the function.
Decrement the reference count in geth_free() to ensure proper cleanup.
