Disable IA32 emulation
Medium Severity
Disables support for legacy 32-bit programs under a 64-bit kernel. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_IA32_EMULATION
, run the following command:
grep CONFIG_IA32_EMULATION /boot/config-*
Configs with value 'n' are not explicitly set in the file, so either commented lines or no lines should be returned.
