CVE-2018-7273

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.

MEDIUM 5.5EPSS 1.76%

Does this matter?

Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.

Description

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.
