seccomp is not set to Docker/Default or Runtime/Default

Description

Secure computing mode (seccomp) is a Linux kernel feature used to restrict actions available within the container. The seccomp() system call operates on the seccomp state of the calling process. The default seccomp profile provides a reliable setting for running containers with seccomp and disables non-essential system calls.
