Medium Severity
Enable this to use virtually-mapped kernel stacks with guard pages. This configuration is available from kernel 4.9. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_VMAP_STACK
, run the following command:
grep CONFIG_VMAP_STACK /boot/config-*
For each kernel installed, a line with value "y" should be returned.
