With six vulnerabilities already being exploited in the wild, another one publicly disclosed, and six labelled as "Critical," it’s not exactly a quiet month for Microsoft's defenders.

Vole's cumulative update patches all six exploited vulnerabilities, meaning one rollout fixes the lot—no extra steps, no post-patch configurations. Five of the six critical vulnerabilities are wrapped up in the same neat package.

The only outlier (CVE-2025-24057) and the publicly disclosed vulnerability (CVE-2025-26630) require Office updates. If you’re using click-to-run, it’s mostly automated, but Office 2016 users must apply two separate patches.

The downside is the sheer weight of these big-ticket vulnerabilities. Twenty-two per cent of this month’s CVEs are critical, exploited, or publicly disclosed.

Reguly said that the low CVE count makes that percentage seem worse but still means more work for IT teams. Perhaps the biggest challenge won’t even be patching—it’ll be fielding nervous questions from managers.

Two other vulnerabilities are worth noting. First, CVE-2025-24064—a remote code execution flaw in DNS—caught my attention. Vole has given it a critical rating but claims exploitation is unlikely.

An attacker needs "perfect timing" to pull it off, and we all know how rare perfection is. Even so, vulnerabilities in core services always warrant a raised eyebrow.

The second is CVE-2025-24061, a Mark of the Web (MotW) issue. It’s not an active zero-day or critical, but previous MotW vulnerabilities have caused headaches, so it’s one to watch.

“This month, the updates are a saving grace, providing a fix to most significant issues with a single update. When this works, it is fantastic. However, the flip side is that when there is a patch issue, all these critical vulnerabilities go unpatched. Keep an eye on the deployment of your cumulative updates and ensure that they deploy without error. Otherwise, this month’s updates could end up worse than they need to be,”  Reguly said.
