In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
usb: gadget: f_midi2: fix use-after-free in string attribute show path<\/p>\n
f_midi2_opts_str_show() takes the string lock internally, but its
\ncallers dereference the opts->info. pointer before calling it,
\noutside the lock. This races with f_midi2_opts_str_store(), which
\nfrees the old string under opts->lock 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.<\/p>\n
Change 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
