"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: midi2: remove default configfs groups on teardown\n\nf_midi2_alloc_inst() creates default configfs child groups for the\ndefault endpoint and default block using configfs_add_default_group(),\nsetting their internal refcount to 1.\n\nHowever, during function teardown in f_midi2_free_inst() or EP cleanup\nin f_midi2_ep_opts_release(), configfs_remove_default_groups() is\nnever called, therefore never dropping the refcount and leaking struct\nf_midi2_ep_opts and f_midi2_block_opts.\n\nAdd the missing configfs_remove_default_groups() in the afformentioned\nfunctions to free the structs properly."
