# PostgreSQL: dict_int buffer over-read leaks server memory to database users

Link for people: https://infrastack.ai/live/CVE-2026-116308 (this .md is for agents)

PostgreSQL's dict_int text search dictionary reads past a buffer when given a zero-length token. A database user with normal query access can read portions of server memory.

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

## How to check

- Run `SELECT version();` in psql and compare against the fixed releases.
- Check whether the `dict_int` extension or dictionary is installed: `SELECT * FROM pg_ts_dict WHERE dict_init::text LIKE '%dict_int%';`

## Fix

- PostgreSQL `18.7`
- PostgreSQL `17.12`
- PostgreSQL `16.16`
- PostgreSQL `15.20`
- PostgreSQL `14.25`

## Timeline

- 2026-11-12T15:41:53+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-116308

## From the sources

Buffer over-read in PostgreSQL dict_int allows a database user to disclose portions of server memory, via a zero-length token.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
