Vulnerability Title
FreeBSD fstatfs 内核函数竞争条件漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
FreeBSD 内核中包含一个fstatfs()函数，用来获取文件系统的状态信息。procfs是进程文件系统，它提供了一个指向系统进程表以及相关数据的文件系统接口。 在fstatfs函数中存在一个竞争条件，可能导致本地内核崩溃，造成拒绝服务。 在调用fstatfs()函数以及某文件被访问之间，该文件可以被删除，这将造成文件描述符变得无效。目前已知procfs文件系统受到此问题影响，当procfs被装载时，本地未授权用户可以造成内核崩溃。
