Fix Recommendation

Configure RHEL 10 to disable virtual system calls with the following command:

$ sudo grubby --update-kernel=ALL --args="vsyscall=none"

Check Contents

Verify RHEL 10 is configured so that the current GRUB 2 configuration disables virtual system calls with the following command:

$ sudo grubby --info=ALL | grep args | grep -v 'vsyscall=none'

If any output is returned, this is a finding.

Check that virtual system calls are disabled by default to persist in kernel updates with the following command:

$ sudo grep vsyscall /etc/default/grub
GRUB_CMDLINE_LINUX="vsyscall=none"

If "vsyscall" is not set to "none", is missing or commented out, and is not documented with the information system security officer as an operational requirement, this is a finding.
