What is CVE-2026-43908?

The OpenImageIO toolset, used for reading, writing, and manipulating various image file formats in visual effects and animation, is affected by an integer overflow vulnerability. Specifically, a flaw within the ConvertCbYCrYToRGB() function results in a signed 32-bit integer overflow in the pixel-loop index calculation, which can lead to an out-of-bounds write. This issue may crash the application or expose it to potential exploits. The vulnerability is resolved in versions 3.0.18.0 and 3.1.13.0, and users should upgrade to these versions to ensure system integrity.
