You then need to wait for your Linux server to boot up again and recover its previous state. Like anyone in the middle of a purchase on your website, for example. You must kick off your users, save your files, and close down processes – at the risk of making a lot of people very unhappy. But there’s a catch: the kernel patch won’t take effect until you reboot. For any RPM-based distribution, including CentOS and Red Hat Enterprise Linux (RHEL), use this:.Sudo apt-get upgrade linux-image-generic sudo reboot On Ubuntu, you can use these commands in a terminal:.It is the method you’ll most likely find in vendor documentation. This is the standard way to do a kernel update using the Linux distribution vendor’s repository. with rebootless live kernel patching tools: Oracle Ksplice Uptrack, Canonical Livepatch, Red Hat’s Kpatch, SUSE Kgraft (SLE Live Patching), and KernelCare Enterprise.I cover three different methods for some of the most popular Linux kernels. This article explains how to update Linux kernels without rebooting. However, it’s a disruptive and time-consuming task because, for Linux, most kernel upgrades and security patches require a system reboot. Keeping Linux instances up to date with the latest operating system and application software patches is one of the most effective ways to strengthen system security and protect against these kinds of cyber threats. Hackers use techniques including remote code execution (RCE), cross-site scripting (XSS), and denial of service (DoS) attacks. Linux’s popularity as a platform for web hosting services, standalone web servers, and web applications makes it a prime target. That’s why finding the best way to patch as fast as you can is so critical. But, leave it too long, and you give an opportunity to threat actors to take advantage of an unpatched vulnerability. There is a lot of work involved in installing the latest Linux kernel security patches, and practical realities can mean that patches are delayed. In most but not all cases, the patches needed to fix them follow swiftly after. But sysadmins must keep patching: newly discovered security vulnerabilities in the Linux kernel seem to appear with monotonous regularity. They are as dull as taxes and about as fun as going to the dentist.
