Linux kernel 竞争条件问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在竞争条件问题漏洞，该漏洞源于内核处理POSIX锁定时fcntl调用可能与关闭相同文件描述符出现竞争，本地攻击者可以利用这个漏洞导致拒绝服务或获得权限提升。 如果其中一个线程仍在fcntl_setlk中阻断期间但在许可锁定之前(在将file_lock结构放置到inode的i_lock列表之前)从另一个线程关闭了文件描述符，关闭路径中的locks_remove_posix调用就会错过POSIX锁定
