Kernel Exploits

Attacks that target vulnerabilities in the operating system kernel.

Understanding:

Kernel exploits target vulnerabilities in an operating system’s kernel (the core component responsible for system control and security). Successful kernel exploitation often results in privilege escalation, bypassing security restrictions, and full system compromise.

Common Applications and Use Cases:

Privilege Escalation Attacks – Attackers gain admin/root privileges by exploiting kernel flaws.
Advanced Persistent Threats (APTs) – Nation-state actors leverage kernel exploits for espionage.
Malware Development – Some malware abuses kernel vulnerabilities to persist undetected.

Best Practices and Security Considerations:

Regularly Update & Patch OS Kernels – Prevents exploitation of known vulnerabilities.
Enable Kernel Security Mechanisms – Use protections like SELinux, AppArmor, and Secure Boot.

Implement Sandboxing & Virtualization – Reduces kernel attack surface.
