Linux Kernel pipe.c空指针引用漏洞
发布日期：2009-11-03
更新日期：2009-11-04
受影响系统：
Linux kernel 2.6.x描述：
BUGTRAQ ID: 36901
CVE(CAN) ID: CVE-2009-3547
Linux Kernel是开放源码操作系统Linux所使用的内核。
Linux Kernel的pipe.c文件中的pipe_read_open()、pipe_write_open()和pipe_rdwr_open()函数存在空指针引用漏洞。在没有保持互斥锁的时候，其他进程可能在没有更新管道的读写计数器之前便释放i_pipe指针，这可能导致本地拒绝服务或权限提升。
