In the Linux kernel, the following vulnerability has been resolved:tcp: Fix use-after-free of nreq in reqsk_timer_handler().The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with__inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler().Then, oreq should be passed to reqsk_put() instead of req; otherwiseuse-after-free of nreq could happen when reqsk is migrated but theretry attempt failed (e.g. due to timeout).Let's pass oreq to reqsk_put().
