  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_midi2: fix use-after-free in string attribute show path\n\nf_midi2_opts_str_show() takes the string lock internally, but its\ncallers dereference the opts-\u003einfo.\u003cfield\u003e pointer before calling it,\noutside the lock. This races with f_midi2_opts_str_store(), which\nfrees the old string under opts-\u003elock when the attribute is written\nconcurrently, the show path can read a pointer that gets freed\nbefore the lock inside str_show() is even taken.\n\nChange f_midi2_opts_str_show() to take a pointer to the string field,\nmatching the existing pattern in f_midi2_opts_str_store(), and\ndereference it only after the lock is held. Update all three callers\n(iface_name, block name, and the EP string option macro) accordingly.",
