Install PAE Kernel on Supported 32-bit x86 Systems
An XCCDF Rule
Description
Systems that are using the 64-bit x86 kernel package
do not need to install the kernel-PAE package because the 64-bit
x86 kernel already includes this support. However, if the system is
32-bit and also supports the PAE and NX features as
determined in the previous section, the kernel-PAE package should
be installed to enable XD or NX support.
The kernel-PAE package can be installed with the following command:
$ sudo yum install kernel-PAEThe installation process should also have configured the bootloader to load the new kernel at boot. Verify this after reboot and modify
/etc/default/grub if necessary.
warning alert: Hardware Warning
The kernel-PAE package should not be
installed on older systems that do not support the XD or NX bit, as
8this may prevent them from booting.8
Rationale
On 32-bit systems that support the XD or NX bit, the vendor-supplied PAE kernel is required to enable either Execute Disable (XD) or No Execute (NX) support.
