漏洞描述
中文描述:

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞,该漏洞源于在5.13.3之前的Linux内核的IPv6实现中,net IPv6输出core.c有一个信息泄漏,这是因为使用了一个哈希表,虽然很大,但没有正确地考虑到基于IPv6的攻击者可利用该漏洞通常可以在许多IPv6源地址中选择。

英文描述:

In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses.
