Enable Yama support
Medium Severity
This enables support for LSM module Yama, which extends DAC support with additional system-wide security settings beyond regular Linux discretionary access controls. The module will limit the use of the system call
ptrace()
. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_SECURITY_YAMA
, run the following command:
grep CONFIG_SECURITY_YAMA /boot/config-*
For each kernel installed, a line with value "y" should be returned.
