This One Patch Isn’t Optional
Microsoft’s latest monthly update closed nearly 400 security flaws. Most of those can wait a few days while your IT team tests and schedules the rollout. One of them cannot.
There’s a bug in a core Windows kernel driver, the low-level code that handles network socket operations. An attacker who already has a foothold on a machine can use it to escalate their privileges all the way to SYSTEM level. That’s full control. At that point, they own the box.
It’s tracked as CVE-2026-68820 and it has a CVSS score of 7.0, which sounds moderate until you realize it’s already being used in active attacks. Real attackers, real targets, right now.
What “Privilege Escalation” Actually Means for Your Business
I get that “privilege escalation” sounds like security jargon. Here’s what it looks like in practice.
An employee clicks a phishing link. Malware lands on their laptop with limited permissions, maybe it can read their files but can’t touch anything system-level. Normally that’s bad but contained. With this vulnerability, that same malware runs one extra exploit and suddenly has administrator access to the entire machine. From there, attackers can disable your antivirus, dump credentials, move to other systems on your network, or deploy ransomware.
That’s the chain. The initial breach doesn’t have to be sophisticated if the escalation is easy.
Who’s Actually at Risk
Every unpatched Windows machine is exposed. That includes workstations, servers, and laptops your staff uses at home if they’re connecting to company resources over VPN.
For a 20-person company in New Jersey, that might mean 20 to 40 endpoints, a couple of on-premise servers, and a handful of remote workers. If any of those machines haven’t received this month’s patches yet, they’re sitting targets.
Attackers don’t always go after Fortune 500 companies. Small and mid-size businesses get hit constantly because the defenses tend to be thinner and the response time slower.
What You Should Be Doing This Week
First, confirm that Windows Update ran on every machine in your environment. If you’re managing updates through Microsoft Intune or Windows Update for Business, pull a compliance report now. Don’t assume everything patched automatically.
Second, check your servers separately. Servers sometimes have longer update windows or manual approval requirements. A file server or application server running an unpatched kernel driver is a serious problem.
Third, look at your remote workers. Laptops that have been sitting in sleep mode or offline for a week may not have pulled the update yet. A quick policy push through Intune can force a check-in and install.
If you’re using Microsoft 365 and Intune together, you can actually see device compliance status from the admin center. It takes about ten minutes to run that report. Do it before the end of the week.
The Broader Pattern Worth Paying Attention To
Nearly 400 patches in a single month is a lot. Microsoft releases these monthly, and the volume has been climbing. Most of the flaws are theoretical, meaning there’s no known exploit in the wild. But a handful each month are actively exploited before the patch even ships.
That gap, between when a vulnerability is discovered and when your machines actually get patched, is where attacks happen. The smaller that window, the safer you are. A well-configured patch management system can get critical updates deployed across your whole environment within 24 to 48 hours of release.
If your current setup can’t do that, it’s worth asking why.
The Concrete Takeaway
Patch this one fast. Run your compliance report in Intune or whatever patch management tool you’re using. Prioritize anything with CVE-2026-68820 still showing as missing. If you have servers, check those manually. If you have remote workers, push a forced update check today.
If you’re not sure how to pull that report or you don’t have a patch management system that gives you visibility across all your endpoints, that’s a gap worth closing. Exine works with small and mid-size businesses across NJ and NYC to make sure these things get handled before they become incidents.
