CVE-2026-41142: OpenEXR is Vulnerable to Integer overflow in ImageChannel::resize leads to heap OOB write via OpenEXRUtil public API

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11, there is an integer overflow in ImageChannel::resize that leads to heap OOB write via OpenEXRUtil public API. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.

Security readout for executives and security teams

Plain-English summary

OpenEXR can corrupt heap memory when resizing image channels through its public utility API. Software that processes untrusted EXR images with affected versions could crash or face compromise risk. Fixed releases are 3.2.9, 3.3.11, and 3.4.11.

Executive priority

Treat as high priority where EXR files cross trust boundaries. Patch exposed ingestion and production media workflows first, then developer and workstation tooling.

Technical view

CVE-2026-41142 is a CWE-190 integer overflow in ImageChannel::resize that can lead to a heap out-of-bounds write through the OpenEXRUtil public API. Affected ranges are 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11.

Likely exposure

Exposure is most likely in media pipelines, rendering tools, image conversion services, asset ingestion systems, or desktop applications that parse EXR files using vulnerable OpenEXR versions.

Exploitation context

The CVSS vector requires user interaction, likely opening or processing a crafted EXR file. The provided bundle says KEV is false, and no cited source confirms active exploitation.

Researcher notes

The source bundle identifies the vulnerable function, affected version ranges, patch versions, CVSS 8.8, and fixing commit/PR. It does not provide confirmed exploitation or product-specific impact beyond OpenEXR and downstream packages.

Mitigation direction

  • Upgrade OpenEXR to 3.2.9, 3.3.11, 3.4.11, or later supported releases.
  • Apply relevant Red Hat advisories where OpenEXR is supplied by Red Hat packages.
  • Restrict untrusted EXR processing until affected systems are patched.
  • Check vendor guidance for downstream applications bundling OpenEXR.

Validation and detection

  • Inventory OpenEXR library versions across servers, containers, workstations, and build artifacts.
  • Identify applications that ingest EXR files from users, partners, or automated feeds.
  • Confirm patched package or library versions are deployed after remediation.
  • Review SBOMs and dependency manifests for vulnerable OpenEXR ranges.
