CVE-2018-7273: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 1.8% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 4.15.4
