Описание
In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small.
An information leak flaw was found in the Linux kernel’s IPv4 implementation in the ip_rt_init in net/ipv4/route.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information.
