CVE-2026-43908
Last modified
CVE-2026-43908 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the pixel-loop index expression i * 3 inside ConvertCbYCrYToRGB() causes the function to compute a large negative pointer offset into the output buffer, producing an out-of-bounds write that crashes the process. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
