CVE-2024-57841

Estado: ModificadaMedia (5.5)—

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

net: fix memory leak in tcp_conn_request()

If inet_csk_reqsk_queue_hash_add() return false, tcp_conn_request() will return without free the dst memory, which allocated in af_ops->route_req.

Here is the kmemleak stack:

Call dst_release() to free the dst memory when inet_csk_reqsk_queue_hash_add() return false in tcp_conn_request().
