Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux kernel 4.5之前版本的kernel/bpf/verifier.c文件中的‘adjust_branches’函数存在安全漏洞，该漏洞源于程序没有考虑backward-jump实例中的delta。本地攻击者可通过创建数据包过滤器并加载BPF指令，利用该漏洞获取内核内存中的敏感信息。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.
