Windows Cloud Files Mini Filter Driver Elevation of Privilege Vulnerability

A patch bypass for this CVE, dubbed MiniPlasma (no new CVE assigned yet), has been identified and a public PoC exists. We are monitoring for exploitation indicators.

The remote Windows host is missing security update 5094127. It is, therefore, affected by multiple vulnerabilities

  - Heap-based buffer overflow in Remote Desktop Client allows an unauthorized attacker to execute code over a     network. (CVE-2026-42909, CVE-2026-42985, CVE-2026-42992, CVE-2026-42993, CVE-2026-44799, CVE-2026-44801,     CVE-2026-47289, CVE-2026-47653, CVE-2026-48563)

  - Arm C1-Ultra, C1-Premium, Neoverse V3 & V3AE, Neoverse V2, Neoverse V1, Neoverse-N2, Neoverse-N1,     Cortex-X925, Cortex-X4, Cortex-X3, Cortex-X2, Cortex-X1 & X1C, Cortex-A710, Cortex-A78, A78AE & A78C,     Cortex-A77, Cortex-A76 & A76A may allow writes to resources owned by a higher exception level.
    (CVE-2025-10263)

  - Heap-based buffer overflow in Microsoft Windows DNS allows an authorized attacker to elevate privileges     locally. (CVE-2026-41108)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
