# AMD Compressonator SDK: crafted DDS file can corrupt heap or crash

The AMD Compressonator SDK has an out-of-bounds write triggered by a specially crafted DirectDraw Surface (DDS) image file. Opening such a file in a user or automated pipeline can corrupt heap memory or cause a denial of service.

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

## How to check

- Check whether the AMD Compressonator SDK is installed or linked into your build or image-processing pipeline.
- Confirm the installed version against the affected range in the NVD entry for CVE-2026-40661: unknown from the sources.

## From the sources

An out-of-bounds write (OOW) condition in the AMD Compressonator SDK could allow an attacker with local access to supply a specially crafted DirectDraw Surface (DDS) file to a user or an automated pipeline, potentially resulting in heap corruption or denial of service (DoS).
