A flaw was found in the Linux kernel’s virtual console resize functionality. An attacker with local access to virtual consoles can use the virtual console resizing code to gather kernel internal data structures.
The attack vector can be significantly reduced by preventing users from being able to log into the local virtual console.
See the instructions on disabling local login here: <https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/managing_smart_cards/pam_configuration_files> , See the section on "pam_console" to deny users logging into the console. This mechanism should work from el6 forward to current versions of Red Hat Enterprise Linux.
