IT Teams: Put the coffee on. It’s a heavy Patch Wednesday

Yesterday’s security updates from Intel, AMD, and Microsoft have landed, and they aren't just "routine maintenance." We are looking at high-severity flaws that target the backbone of the enterprise: Data Centers, Domain Controllers, and DNS Servers.

Here is the breakdown of what needs your immediate attention:
1. The Silicon Giants (Intel & AMD)
Intel: 13 advisories covering 24 defects. The headliner is CVE-2026-20794(CVSS 9.3). It’s a buffer overflow in Data Center Graphics Drivers that could lead to Remote Code Execution (RCE).
AMD: A massive haul of 46 patches. The focus here is on side-channel mitigations and privilege escalation flaws across multiple processor lines.

2. Microsoft’s "Critical" List
Redmond dropped patches for 138 vulnerabilities this month. Two in particular are "drop everything" fixes:
a- Windows DNS Server (CVE-2026-41096): A heap-based buffer overflow with a CVSS of 9.8. This allows unauthenticated RCE. If your DNS is exposed, you are at high risk.
b- Windows Netlogon (CVE-2026-41089): Also a 9.8 CVSS. This flaw allows an attacker to take over a Domain Controller via a crafted network request.

The Bottom Line:
With multiple 9.0+ CVSS scores in play, the window for exploitation is small. Prioritize your Domain Controllers and DNS infrastructure first, then move to your data center hardware.
