Title: Linux kernel本地拒绝服务漏洞（CNVD-2016-13294）

Description:

Linux kernel是美国Linux基金会发布的操作系统Linux所使用的内核。

Linux kernel 3.4.99及之前的版本中的net/core/sock.c文件的‘sock_setsockopt’函数存在安全漏洞，该漏洞源于程序未能正确的处理‘sk_sndbuf’和‘sk_rcvbuf’的负值。本地攻击者利用该漏洞可借助带有SO_SNDBUF或SO_RCVBUF选项的setsockopt系统调用造成拒绝服务（内存破坏和系统崩溃）。

Severity: 低

Severity ?

CWE

Summary

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option.
