# Windows TCP/IP: heap overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-96102 (this .md is for agents)

Heap-based buffer overflow in the Windows TCP/IP stack lets an authorized local attacker raise privileges (CVSS 7.8 High per CVE listing). Affected Windows builds, fixed KBs and exploitation status could not be read from Microsoft's page yet.

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

## Affected

- vendor:Windows TCP/IP affected range not listed fixed no fixed version listed

## How to check

unknown: Microsoft's update guide entry for CVE-2026-96102 lists the affected builds and KBs. Until read, treat any Windows machine missing the latest cumulative update as possibly exposed; check with winver or Get-HotFix.

- 2026-11-10T19:48:22+00:00 analyst — MSRC update-guide page is JS-only and returned empty via web-cli/WebFetch; NVD page empty too. Only a CVE listing (casco.com) confirms: heap-based buffer overflow in Windows TCP/IP, local EoP, CVSS 7.8 High, updated 2026-11-10. No affected builds, KBs, exploitation status or mitigations found; sibling Oct 2026 TCP/IP CVEs (96852, 83842) have different build lists and were not applied. Nothing verified. Settle by reading the MSRC page in a browser or its CSAF/API entry.

## From the sources

Heap-based buffer overflow in Windows TCP/IP allows an authorized attacker to elevate privileges locally.
