Vulnerability Title
N/A
Vulnerability Description
An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR.

Linux kernel 安全漏洞
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。 Linux kernel 4.15.7及之前版本中的drivers/block/floppy.c文件的‘fd_locked_ioctl’函数存在安全漏洞。攻击者可通过发送FDGETPRM ioctl并借助获取的内核指针利用该漏洞获取内核代码和数据的位置，绕过内核安全保护（例如：KASLR）。
