No Reboot Required
Removing Disruptions and
Downtime from Linux Patching
Kernel vulnerabilities create a familiar problem for Linux teams. The fix exists, but applying it the traditional way means installing a new kernel and rebooting the system.
That turns a routine security update into a maintenance event: scheduling, change approval, application owners, downtime risk.
And the systems that most need patching are often the hardest to restart, from production databases and clustered workloads – not to mention edge fleets and anything carrying an uptime commitment. A distribution can ship a fix within days and still leave a gap between the vulnerability being fixed and your systems being protected.
Rebootless patching closes that gap differently. Fixes are applied to a running kernel in memory, so exposure ends when the patch lands rather than when the next window opens. It also raises fair questions about how those patches are built, tested, and trusted, and about which fixes can be delivered this way at all.
Join TuxCare alongside the AlmaLinux OS Foundation for a practical look at how rebootless patching works, where it fits in Linux security operations, and what happens between a kernel vulnerability being disclosed and a fix reaching production.
During this webinar, you’ll learn:
- How rebootless patching applies security fixes to a running Linux kernel, and what still requires a restart.
- What happens between disclosure and deployment (patch development, backporting, testing, and repository rollout).
- Where reboot requirements create operational delay, and why a fast upstream fix doesn't always mean fast protection.
- How to decide where rebootless patching complements your existing Linux update and change-management process.
This session is designed for:
- Linux administrators responsible for patching production systems
- Platform, infrastructure, DevOps, and SRE teams managing uptime-sensitive Linux environments
- Security and compliance teams accountable for vulnerability remediation timelines, exposure windows, and audit evidence
- IT and engineering leaders balancing security requirements against availability and maintenance constraints
Why Watch?
A kernel patch being available and a production system being protected are not the same thing.
This session looks at that gap from both sides: how Linux distributions build, test, and ship security fixes, and how teams can apply kernel updates without turning every vulnerability into a maintenance-window decision.
