Disable support for /proc/kkcore
Low Severity
Provides a virtual ELF core file of the live kernel. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_PROC_KCORE
, run the following command:
grep CONFIG_PROC_KCORE /boot/config-*
Configs with value 'n' are not explicitly set in the file, so either commented lines or no lines should be returned.
