Vulnerability Description
The mq_open system call in Linux kernel 2.6.9, in certain situations, can decrement a counter twice ("double decrement") as a result of multiple calls to the mntput function when the dentry_open function call fails, which allows local users to cause a denial of service (panic) via unspecified attack vectors.

Linux Kernel mq_open系统调用拒绝服务漏洞
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对目录操作的实现上存在漏洞，本地攻击者可能利用此漏洞对系统进行拒绝服务攻击。如果dentry_open函数调用失败的话，就会多次调用mntput函数。Linux Kernel的mq_open系统调用在这种情况下就可能两次递减计数器，这就允许本地攻击者导致系统忙碌，造成拒绝服务。
