What is CVE-2026-40918?

A significant vulnerability has been discovered in GIMP, specifically in the handling of specially crafted PVR image files. When processing these large-dimensional files, a stack-based buffer overflow may occur, resulting in an out-of-bounds read in the image loader. This flaw ultimately leads to a denial of service, causing the application to crash. Systems utilizing GIMP to process untrusted PVR image files are particularly susceptible to this issue, highlighting the importance of exercising caution when handling such files.
