  Executive Summary Linux systems continue to face 0-click (no-interaction) vulnerabilities — bugs that allow attackers to compromise a machine without user action. These may be local privilege escalations (e.g., PwnKit ) or network-triggered RCEs (e.g., ksmbd / SMB kernel flaws ). Because they bypass human interaction, they are high-value to attackers and require proactive defense . This guide outlines 7 practical, PRO-grade steps for admins and security teams to mitigate these threats. Step 1 — Patch & Update Relentlessly Apply distro security patches for kernel, Polkit, and SMB services immediately. Subscribe to CISA KEV and vendor advisories to catch newly exploited Linux CVEs. Automate patch pipelines where possible. Step 2 — Minimize Attack Surface Disable unused network services (SMB, NFS, RPC) that are common 0-click entry points. Remove or restrict SUID binaries that attackers exploit locally (e.g., pkexec ). Harden SSH: disable password ...
