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 2.6.34之前版本中的IP GRE模块中存在空指针解引用拒绝服务漏洞。GRE协议receive钩挂例程可在完成协议添加后被调用。如果netns stuff尚未初始化，会导致net_generic()中的崩溃。如果ip_gre编译成了模块并且在加载该模块时收到了包，也会导致远程崩溃，拒绝服务合法用户，也可能执行任意代码。
