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 4.4.1之前版本的sound/core/timer.c文件中存在安全漏洞，该漏洞源于程序使用没有考虑slave定时器实例的锁定方法。本地攻击者可借助特制的ioctl调用利用该漏洞造成拒绝服务（竞争条件，释放后重用和系统崩溃）。
