Vulnerability Title
N/A
Vulnerability Description
The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

Linux kernel execve函数本地拒绝服务漏洞
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的execve函数没有清除current->clear_child_tid指针，在处理线程创建和退出过程中启用了CLONE_CHILD_SETTID或CLONE_CHILD_CLEARTID的clone系统调用会导致内存破坏。本地攻击者可以利用这个漏洞导致拒绝服务。
