kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak

The Linux kernel's TCP source port generation algorithm in the TCP stack contains a flaw due to the small table perturb size. This flaw allows an attacker to positively distinguish a system among devices with identical hardware and software, which lasts until the device restarts. An attacker can...
