Vulnerability Description
The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device.

Linux kernel‘raw_cmd_copyout’函数权限许可和访问控制问题漏洞
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 3.14.3及之前版本的drivers/block/floppy.c文件中的‘raw_cmd_copyout’函数存在安全漏洞，该漏洞源于当处理FDRAWCMD ioctl调用时，程序没有正确限制对指针的访问。本地攻击者可借助/dev/fd设备的写访问权限利用该漏洞获取内核堆内存的敏感信息。
