Senserva AI Opinion for CVE-2025-48810

A second, independent Secure Kernel Mode disclosure, separate from CVE-2025-48809, affects the same Windows Server 2025, Server 2025 Core, and Windows 11 24H2 ARM64 systems at Critical 9.8 with 22 percent EPSS. Two Secure Kernel Mode bugs in one release means VBS-protected systems should get closer attention this cycle than usual, and both fixes likely arrive in the same cumulative update. Validate coverage of both CVE numbers after patching.

Do this: Confirm the cumulative update resolves both Secure Kernel Mode CVEs, this one and CVE-2025-48809, on the affected 25 and 24H2 builds.
