Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.15.4
Description The issue is related to the floppy driver in the Linux kernel, specifically the show floppy function in drivers/block/floppy.c. This function uses printk calls to reveal the addresses of kernel functions and global variables. An attacker can read this information from dmesg and use the addresses to find the locations of kernel code and data, potentially bypassing kernel security protections. The exploitation of this issue may allow an attacker to bypass kernel security and gain unauthorized access to protected information.
Recommendations For Linux kernel versions prior to 4.15.4, update to a version that contains a fix for this issue to prevent potential exploitation.
