I'm trying to understand how security differs between LTS, stable, and rolling-release Linux distributions. Linux Mint is based on Ubuntu LTS, while Ubuntu itself draws from Debian, and I've come across claims that older or long-term-supported packages can become more vulnerable over time.
My understanding is that LTS does not mean packages are abandoned. Security fixes are usually backported to supported versions, while major feature changes and potentially disruptive updates are held back. However, I'm unsure how comprehensive that process is, especially for large repositories and packages that are no longer actively maintained upstream.
Does a slower release cycle actually make a distribution less secure, or does it mainly improve stability? Are rolling-release distributions safer because they receive newer fixes and architectural changes sooner? How do distribution maintainers handle vulnerable, orphaned, or unsupported packages, and what practical security differences should a typical desktop user expect between systems such as Linux Mint, Debian, Ubuntu LTS, Fedora, or a rolling-release distribution?

For most desktop users, the largest risks are often unsafe downloads, pirated or modified software, weak passwords, exposed services, phishing, and missing updates—not simply choosing a stable distribution. Keep automatic security updates enabled, use the official repositories or well-established packaging systems, avoid running daily work as root, enable a firewall when appropriate, and maintain tested backups.
You can also check the support lifecycle for your exact release and review security advisories from the distribution. No update schedule protects against unknown vulnerabilities, so reducing unnecessary software and limiting network services is useful regardless of whether the system is LTS, stable, or rolling.
