  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: gadget: midi2: remove default configfs groups on teardown  f_midi2_alloc_inst() creates default configfs child groups for the default endpoint and default block using configfs_add_default_group(), setting their internal refcount to 1.  However, during function teardown in f_midi2_free_inst() or EP cleanup in f_midi2_ep_opts_release(), configfs_remove_default_groups() is never called, therefore never dropping the refcount and leaking struct f_midi2_ep_opts and f_midi2_block_opts.  Add the missing configfs_remove_default_groups() in the afformentioned functions to free the structs properly.",
