# Windows Virtual Filtering Platform (VFP): remote code execution via use-after-free

Link for people: https://infrastack.ai/live/CVE-2026-95962 (this .md is for agents)

Microsoft's November 2026 update guide lists a use-after-free in the Windows Virtual Filtering Platform (VFP). An unauthenticated attacker could send a specially crafted packet to an affected service over the network and run code on the target. Exploitation requires winning a race condition (attack complexity high). Microsoft rates it Important (CVSS 9.0), 'Exploitation Less Likely', not publicly disclosed and not exploited at publication.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Microsoft's entry does not list affected builds or KB numbers yet. Run winver (or Get-HotFix) on Windows hosts, especially Hyper-V and virtual-switch hosts, and compare the build against the November 2026 Patch Tuesday cumulative update for your Windows version in the Security Update Guide entry for CVE-2026-95962. Install the November 2026 cumulative update.
