# Intel Neural Compressor: untrusted deserialization lets a local user crash the app

Link for people: https://infrastack.ai/live/CVE-2026-50177 (this .md is for agents)

Some Intel Neural Compressor software before version 3.8 deserializes untrusted data without checks. A local user with an ordinary account can trigger it to cause a denial of service.

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

## How to check

- Check the installed Intel Neural Compressor version with `pip show neural-compressor` or the version in your environment.
- Confirm whether any version below `3.8` is installed on shared or multi-user machines.

## Fix

- Move Intel Neural Compressor to `3.8` or later.

## From the sources

Deserialization of untrusted data for some Intel(R) Neural Compressor software before version 3.8 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
