Summary
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:
unreferenced object 0xffff8881198631c0 (size 240):
comm "softirq", pid 0, jiffies 4299266571 (age 1802.392s)
hex dump (first 32 bytes):
