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 3.7.4和较早版本中的Reliable Datagram Sockets (RDS)协议实现中的net/rds/ib_send.c中的rds_ib_xmit函数中存在漏洞。通过建立带有与IPoIB接口本身IP地址相同的源IP地址的RDS连接，本地攻击者利用该漏洞导致拒绝服务（BUG_ON和内核崩溃）。

Vulnerability Description
The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB interface's own IP address, as demonstrated by rds-ping.
