Warning Message: memfd_create() called without MFD_EXEC or MFD_NOEXEC_SEAL set

Linux 6.6 LTS introduced additional security measures to protect against write/executable memfd_create syscalls. This warning message is simply to warn users that a specific application is using the old memfd_create syscall without the new security parameters. It is not consequential and does not affect the running of said application.
