# Windows DirectMusic: double free lets a network attacker run code

Link for people: https://infrastack.ai/live/CVE-2026-95901 (this .md is for agents)

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

## How to check

Unknown until Microsoft lists affected builds. Open the MSRC Security Update Guide page for CVE-2026-95901, find the KB for your Windows version, and compare it with the installed build (winver, or Get-HotFix in PowerShell).

## Timeline

- 2026-11-10T19:25:23+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-95901
- 2026-11-10T19:27:21+00:00 analyst — Could not read the MSRC advisory body (JS page rendered only the title 'Microsoft DirectMusic Remote Code Execution Vulnerability'; web-cli returned nothing; NVD page also empty). Search results only cover sibling CVE-2026-69491 (heap overflow, Sept 2026), not this one. No builds, KB or fix confirmed. Revisit when MSRC/NVD text is indexed; nothing verified.

## From the sources
