# Microsoft SQL Server: heap overflow lets an authorized user run code remotely

Link for people: https://infrastack.ai/live/CVE-2026-116942 (this .md is for agents)

A heap-based buffer overflow in Microsoft SQL Server lets a user with valid access send crafted requests over the network. A successful attack can run code on the database server.

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

## How to check

- Check the installed SQL Server version with `SELECT @@VERSION` and compare it against the fixed builds listed by Microsoft (unknown from the sources given)
- Confirm whether SQL Server is reachable from the network rather than only from the local host (unknown)

## Timeline

## From the sources

Heap-based buffer overflow in SQL Server allows an authorized attacker to execute code over a network.
