In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: f_midi2: fix use-after-free in string attribute show path

f_midi2_opts_str_show() takes the string lock internally, but its

callers dereference the opts->info.<field> pointer before calling it,

outside the lock. This races with f_midi2_opts_str_store(), which

frees the old string under opts->lock when the attribute is written

concurrently, the show path can read a pointer that gets freed

before the lock inside str_show() is even taken.

Change f_midi2_opts_str_show() to take a pointer to the string field,

matching the existing pattern in f_midi2_opts_str_store(), and

dereference it only after the lock is held. Update all three callers

(iface_name, block name, and the EP string option macro) accordingly. (NVD)
