Description:
7
 
 An issue was discovered in the fd_locked_ioctl function in
8
 
 drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy
9
 
 driver will copy a kernel pointer to user memory in response to the
10
 
 FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the
11
 
 obtained kernel pointer to discover the location of kernel code and data
12
 
 and bypass kernel security protections such as KASLR.
13
 
Ubuntu-Description:
14
 
 It was discovered that an information leak vulnerability existed in
15
 
 the floppy driver in the Linux kernel. A local attacker could use
16
 
 this to expose sensitive information (kernel memory).
