A Linux kernel flaw gives local users root where user namespaces are open. Public exploit code exists. No fixed kernel yet.

Check: sysctl user.max_user_namespaces

0 closes the path, no reboot. Rootless containers and LXC stop working for ordinary users.

A hacked site on a VPS isn't a one-ticket job. It’s triage, cleanup, customer back-and-forth, and a repeat visit.

Is that support time in your VPS margin math?

HostArmada reported a 70-80% drop in hacked-site tickets on VPS with Imunify360.

The kernel patch was ready on Tuesday. The reboot was scheduled for Saturday night.

For kernel CVEs, the patching delay was never about the fix. It was about the reboot.

Here's the breakdown: https://t.co/V3J93JKFA0

What does your rebooting actually cost?

A critical WordPress plugin flaw drew exploits the morning after its fix was shipped.

Two weeks later, 84% of affected sites we monitor still hadn't patched.

Most server trials are wasted on a quiet test VM: click around, let it expire.

Test any hosting OS under load. Spike an account on a real server to see if anyone else notices.

Hosting Ireland and LetsHost ran shared and VPS on two stacks. Now they run both on CloudLinux and Imunify360.

One training track. The same fix on both platforms. One team covering everything.

How long does a new hire take to be useful on two stacks?

Installed ≠ protected.

A kernel patch does nothing until a reboot. But rebooting takes every customer site offline, so it waits.

Attackers get in through the gap.

KernelCare patches the running kernel. No downtime.

Rebootless live patching is amazing: https://t.co/qgusd0bBPU

16 named Linux kernel exploits went public in 16 weeks this year.

The real issue isn't the CVE count but the same poor choice: patch now (reboot risk) or wait (stay exposed).

New in beta, Phase 3 of CloudLinux Isolates: each isolated website can now have its own CPU, memory and I/O limits, so a busy site is throttled on its own. The account's limit still caps the total. https://t.co/YE8uZ2Cc0l

35% of hosting support time goes to performance issues. Usually, one account spikes and slows everyone else down.

CloudLinux's LVE keeps that account's spike contained.

Stop selling boxes. Start selling VPS plans.

Root access is a feature. Account isolation and automated security are the plan: @HostArmada cut hacked-site tickets 70–80% after deploying Imunify360.

Build the plan, not the spec sheet: https://t.co/HQg84aM6mE

@Duplika made @CloudLinuxOS + @Imunify360 standard on every VPS plan in under a month. Fewer complaints, more time for hands-on support.

Two VPS tickets exist: “it’s slow” and “we’ve been hacked.”
You’ll get both this quarter.

Add CloudLinux + Imunify360 in the plan and fewer of them arrive. https://t.co/6aLHwKZw9k
