Hi,

The following vulnerability was published for gimp.

CVE-2026-96546[0]:
| A one-byte out-of-bounds heap read flaw was found in GIMP's
| uncompressed DDS image loader. When a user opens an uncompressed DDS
| image, the file-dds plug-in performs an unconditional one-byte look-
| ahead after processing the final pixel. This may cause the plug-in
| to crash if the byte immediately following the pixel buffer is
| inaccessible; no information disclosure or code execution has been
| demonstrated.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
