Senserva AI Opinion for CVE-2025-54105
This flaw sits in the Microsoft Brokering File System that mediates file operations on Windows Server 2025 Server Core, Server 2022 23H2 Server Core, and 24H2-based Windows 11 ARM64 builds, and a successful exploit hands a local user full privilege escalation. With a CVSS of 8.8 and roughly a one in five chance of exploitation per EPSS, it is not the most urgent Windows patch this cycle, but skipping it leaves a live local privilege path on the newest server builds.
Do this: Prioritize this patch on Server 2025 and Server 2022 23H2 Server Core hosts, since Server Core boxes often lag standard patch cycles.
