A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem.
The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
