Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.16.4rc4

Description: The issue allows local users to obtain sensitive address information by reading specific lines in a debugfs file. This is due to a problem in the aoedisk debugfs show function in drivers/block/aoe/aoeblk.c.

Recommendations: For Linux kernel versions prior to 4.16.4rc4, consider restricting access to the debugfs file to minimize the risk of exploitation. As a temporary workaround, limiting read access to "ffree: " lines in the debugfs file may help until a patch is available.
