Medium Severity
Enable tasks to build secure computing environments defined in terms of Berkeley Packet Filter programs which implement task-defined system call filtering polices. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_SECCOMP_FILTER
, run the following command:
grep CONFIG_SECCOMP_FILTER /boot/config-*
For each kernel installed, a line with value "y" should be returned.
