Anyone working in Linux security right now is being kept very busy.
While that’s been the case for a few years, it’s particularly true right now because the Linux kernel team published 432 Common Vulnerabilities and Exposures (CVE) in one 24-hour span last week.
Dealing with the deluge
Headlines about 400+ Linux CVEs is eyebrow raising stuff, but you don’t need to panic. The good news for SiteHost customers with Cloud Containers and managed servers is that nothing really changes for you.
The Linux kernel is an important part of server infrastructure—it’s the open-source core of any Linux OS. Any published CVE affecting the Linux kernel is something we take seriously. In that respect, this is nothing new for us. Patching these vulnerabilities is part of the routine.
No provider has to worry about every CVE, and our team is busy patching (or has already patched) all the vulnerabilities affecting your servers.
We’re being strategic with our approach, and doing what we can to minimise the amount of downtime and restarts needed. Maintenance plans have been scheduled and shared with affected customers.
An extra 432 Linux CVEs means more patching in a shorter time than we’d normally do, but other than the dramatic number, it’s nothing unmanageable for a team like ours.
This keeps on happening
In 2025 there were significantly more CVEs published than in any year prior. We expected this trend to continue when we wrote about the rising CVE numbers earlier this year.
It has.
Back then we were averaging over 100 new CVEs published every day. This new barrage of 432 Linux CVEs is still within that baseline. There will always be spikes and troughs in CVE reporting, and this is one particularly sharp spike.
While it’s tricky to deduce how every CVE was spotted, LLM discovery tools are widely speculated to be responsible for the increased vulnerability reporting. AI-powered Xint Code was responsible for uncovering the Copy Fail vulnerability earlier this year, which we also promptly patched on our Cloud Containers and managed servers.
As these AI tools inevitably get more powerful and more accessible, it’s likely these breakthroughs will become more frequent. The only way to stay on top and remain secure is to keep patching systems for relevant CVEs as they roll in.
In the case of these 400+ CVEs arriving at once, it seems it was caused by a Linux kernel maintainer clearing their review backlog after a long holiday, rather than a revolutionary engineering breakthrough. Regardless of how they got here, 400+ CVEs arriving on our desk in one day certainly grabbed our attention.
This isn’t just a Linux thing, and it’s far from over
The vulnerabilities we’re talking about here are all related to the Linux kernel, but it’s not a problem exclusive to Linux. On a given Tuesday in July Microsoft casually published 622 CVEs.
Whatever shape your server takes, the battle against CVEs is only getting bigger. If maintaining your own server against an ever-growing horde of CVEs sounds like a tough gig—you’d be correct.
This latest CVE flood is another reminder of the benefits of Server Management. We have a 24/7 team of skilled engineers handling the ongoing bombardment of CVEs smartly and calmly.
Alongside security patching, monitoring and maintenance, Server Management also gives you much needed peace of mind. With Server Management, headlines about 400+ new CVEs don’t change your plans at all because you know we’re handling it.
If you’d like to talk with us about adding Server Management, we’re always here to help.
