Vulnerability Title
N/A
Vulnerability Description
The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call.

Linux kernel 拒绝服务漏洞
Vulnerability Description
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/seq/seq_clientmgr.c文件中的‘snd_seq_ioctl_remove_events’函数存在安全漏洞，该漏洞源于程序进行FIFO清除时没有验证FIFO分配。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（空指针逆向引用和OOPS）。
