What is CVE-2018-1122?

Procps-ng prior to version 3.3.15 is susceptible to local privilege escalation when the 'top' command is executed in an environment where the HOME variable is unset. If an attacker controls the directory from which 'top' is run, they can exploit flaws in the config_file() function, potentially gaining higher privileges on the system. This vulnerability underscores the importance of secure configuration practices and environment variable management in Linux systems.
