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; otherwise use-after-free of nreq could happen when reqsk is migrated but the retry attempt failed (e.g. due to timeout).
Let's pass oreq to reqsk_put().
