This security feature restricts access to certain kernel features, making it more difficult for an attacker to escalate privileges or modify the kernel. It was introduced in Linux kernel 5.4, back in 2019, and has been improved in subsequent releases. As of 2026, Kernel Lockdown Mode is a mature feature that can be easily enabled on most Linux distributions.</p>
