Floppy Driver Information Disclosure Vulnerability

CVE-2018-7273 · MEDIUM Severity

AV:L/AC:L/AU:N/C:C/I:N/A:N

In the Linux kernel through 4.15.4, the floppy driver reveals the addresses of kernel functions and global variables using printk calls within the function show_floppy in drivers/block/floppy.c. An attacker can read this information from dmesg and use the addresses to find the locations of kernel code and data and bypass kernel security protections such as KASLR.
