What is CVE-2026-106066?

A heap-based buffer overflow has been identified in GIMP's raw data export plug-in. This vulnerability occurs when exporting very large images, as the memory allocation through g_malloc() uses an incorrectly calculated size based on width, height, and bytes-per-pixel. An integer overflow can lead to insufficient memory being allocated compared to the amount required during export operations, creating a potential risk during image processing tasks.
