What is CVE-2026-96546?

A one-byte out-of-bounds heap read vulnerability exists in GIMP's uncompressed DDS image loader. When an uncompressed DDS image is opened, the file-dds plug-in initiates a one-byte look-ahead after processing the final pixel. If the byte following the pixel buffer is inaccessible, this can trigger a crash of the plug-in. Although this issue could disrupt functionality, it does not result in information disclosure or code execution.
