This CVE is among the top half of tracked Microsoft CVEs by EPSS exploit probability.
The storage port driver, which underlies disk I/O, carries this Critical 9.8 disclosure across Windows Server 2025 Server Core, Windows Server 2022 23H2 Server Core, and Windows 11 Version 24H2 on ARM64, with EPSS at 36 percent, matching the elevated exploitation forecast of the kernel bug above. Storage drivers operate at a low level with broad system access, so an exploit chain built on this leak could be attractive to attackers targeting storage infrastructure specifically. Prioritize alongside the other 36 percent EPSS item in this release.
Do this: Patch Server 2025 Core, Server 2022 23H2 Core, and Windows 11 24H2 ARM64 hosts for this storage driver issue in the near-term patch window.
